Probably after the last update I am not able to simply do "Folder Maintenace" by File > Do Folder Mainenace. After doing this the process gives an error message:

"You cannot maintain the "Recycle Bin in xxx@xxx.net" folder because you cannot write to the folder. Check that you have enough disk space and write permissions to the folder and repeat the action.

This started to happen simultaneously on all my devices (two PCs, one notebook), all with updated Windows 11 and with last version of Thunderbird (128.5.2esr (64 bit) and also both in my personal and working mail domains. All of them are IMAP.

If I try to maintain only the trash bin separately, it takes a long time and finishes without any error message. But trying after that the complete maintain again fails.

I tried to delete trash files from the account profile on the disc and then it work. But only until I deleted any message. Then the problem ocurred again.

I am not sure whether I am doing good or bad to maintain folders regularly, but it was okay and without problems yet around month ago, not now.

Thank you, Michal

Issue 1: As with vimium(https://chromewebstore.google.com/detail/vimium/dbepggeogbaibhgnhhndojpepiihcmeb?hl=en&pli=1) extension we can press J or K to more left or right, or in Zen browser's case, up and down. But vimium has limitation as it doesn't run on Zen's native web points like settings homepage etc. Please add a shortcut for navigation between tabs other than alt 1-9. Where we can just change adjacent tabs.

Issue 2: Also on full screen the bookmark bar it impossible to access with shortcut or without it just vanishes

Issue3: The browser close minimize icon are just useless on full screen I3WM or HyprLand like windows manager as we never need to do those things.

Issues are arranged in their priority order, as the top one needs the most focus from the devs.

Recently, Firefox on my MB Pro (M1) has been freezing up or drastically slowing down due to "FirefoxCP Isolated Web Content" processes (multiple). What is this? How do I fix it? Is this a deal breaker for using Firefox as my default Mac browser?

My calendar won't save a new entry (and has no entries). How do I remove and reinstall (refresh) the calendar? Thanks for any help. My Thunderbird is 128.4.4esr (64-bit). My OS is Ubuntu 24.04.1

Good day. I'm thinking of deleting Firefox. It's simply impossible to use it on some sites. For example, I can't write a comment on YouTube because the browser freezes. Page scrolling and controls also freeze. I turned off browser extensions, but it doesn't help. I have 48GB of DDR5 memory and one of the best processors available today...

Pixel 8a on google fi flexible plan Yesterday I was at work and got a notification of high data usage and at the same time a 3gb warning message. I checked my phone and it showed a 5gb spike of data to firefox. I was not actively using firefox at the time. Is there a way I can track down what it did? A logfile that could give me a clue? Fi charges me $10 a gb so this is more than a little annoying.

Also it's very upsetting it went to mobile data when I had an active wifi connection.

When I log in with one of my screen names on AOL, it shows me signed in under that screen name, but when I click to open the mail for that screen name, I am changed to another one of my screen names with only the mail showing for that account instead of the one I initially signed in on. I have uninstalled and reinstalled Firefox, cleared the cache, but the problem continues. I do not have this problem when I log in to AOL on Chrome with the same screen name. AOL technical support was unable to figure out how to fix this problem. I am using a brand new laptop with Windows 11 Pro. I do not have this problem with an older computer with Firefox.

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions. It's like I have a corrupted Codec or something. Does anyone have any suggestions? Thanks.

Lately I have been having an issue on Firefox with YouTube stopping and buffering after one minute. This occurs on all videos but only on Firefox. YouTube runs fine on other browsers.

I have tried changing the resolution and disabling ad blockers, but without resolving the situation. I am using the most recent build of Firefox. I have also expanded the size of the cache (after clearing it), but that did not help.

I can't seem to find any real help with this online, and I would appreciate any assistance anyone can give me.

Thanks!!

i am trying to play a game on cool math games and the game keeps hanging. i also have issues on another site where the video player indefinitely loads. and yes i have cleared cookies and site data, disabled all extensions, started firefox in troubleshot mode, disabled hardware acceleration. but the only thing that fixes the issue is using another browser.

how to reproduce

1: go to this url: https://www.coolmathgames.com/0-jacksmith 2: load the game and start a save 3: skip or wait through the dialog (i did both) 4: when the dialog ends you should be stuck with a folded piece of paper on the side of the screen when the animation froze. loading the save will also cause a freeze

I have a long-standing problem with items in my Mozilla calendar sometimes disappearing after I open my Outlook calendar on my cell phone. The items continue to show in the Outlook calendar on my phone and in Google Calendar online, both of which are connected to my Mozilla calendar. Any ideas or suggestions? Thanks in advance for the help!

The menu bar keeps flashing about every 5-10 seconds. When it does it disrupts / interrupts whatever I'm typing, deleting everything I've typed when the flash occurs.

It also disrupts things like using a drop down menu. The menu is opened (aka dropped down) but when the flash occurs it collapses the drop down menu.

Also for example en typing; let's say I'm typing " Mary had a little lamb". After typing "Mary had a" the Menu bar flashes. When it does "Mary had a" gets deleted. As I continue to type not knowing "Mary had a" was deleted I look up and see all that's left is "little lamb".

It's constantly doing this even while typing this message / question.

If copy and pasting it'll clear the text I've chosen to copy so I have to go back and re-select it. And try to get it done quickly before the next flash occurs. But if the next flash occurs the same thing happens all over again.

I have no idea what's going on. Searched and searched and can't find anything. It's making Firefox almost impossible to use. Please help me?!

I'm using Firefox version 115.18.0esr It is up to date.

My bookmarks get strewn above the toolbars, they dance back and forth, the program won't work and on the few occasions the homepage opens without these interruptions, the home prompt launches the problem all over. when it's in this mode nothing responds. I have to crash it to be able to use other applications. It's been going on for a long time and I'm ready to throw the baby out with the bathwater. Any ideas out there???

Hello.

For the past few months, I've been experiencing severe issues with performance that I noted appear only on YouTube. I have not noticed this on any other website. The site is unresponsive, takes a long time to load, key presses (pause, skip 10s, etc.) are registered with a massive delay. It is generally very unpleasant to use.

I have tried disabling all extensions, clearing data, I even reinstalled the entire operating system once for a different reason and the issue still persisted. I launched YouTube on different browsers (Chrome) with no performance issues at all.

I lived with this problem for a long time now, but recently it's becoming unbearable. I prefer Firefox to Chromium-based browsers, but as YouTube is a site I visit very frequently, I will unfortunately consider switching to another browser.

I have not found any useful resources regarding this issue on the Internet, it seems like it's not a common problem.

Any help is appreciated.

Fire Fox is shown in the Task Bar. When selected, a new tab opens the desktop. I prefer using the shortcut display under the Fire Fox logo with two rows of internet selections. When the Task Bar Fire Fox icon is selected, Fire Fox opens as expected. However, if I select any item on the open page, a second Fire Fox icon appears in the taskbar but without the same pinned shortcuts on the preferred Fire Fox page. How is this second, unwanted page to be removed.

I've read about this problem in posts that are twenty years old and hesitate to follow that advice. Thank you in advance for a solution to this annoying problem.
