Firefox Support Forum

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Problem: When exporting or downloading content from the GUI in the digital forensics tool Velociraptor, underscores are appended to the beginning and end of filenames. File is otherwise downloaded correctly, but removal of underscores necessary if original filename is desired. One hypothesis is that perhaps for security reasons there were changes made in Firefox 127 for how character escaping is performed.

Tested Operating Systems: Ubuntu 24.04, Windows 11 22H2, Windows 11 24H2, macOS Sonoma (14.5) Affected Firefox version(s): Confirmed 127.0, 127.0.1, 127.0.2 Tested Firefox versions which do not reproduce the behavior: 126.x, 125.x > Testing Microsoft Edge, Chromium, Google Chrome on Windows, macOS, Linux: files download with correct name as expected. Testing performed with clean installations on clean VMs with no add-ons enabled.

To reproduce: Download the latest release of Velociraptor from Github (at the time of this writing, 0.72.3) for preferred platform / operating system. Run Velociraptor using the gui switch, e.g. "$sudo velociraptor-v0.72.3-windows-amd64 gui" or "$ velociraptor-v0.72.3-windows-amd64.exe gui" Navigate to Server Artifacts and click the "+" icon at the top Search for Server.Utils.CreateMSI - select and press Launch Select the newly-created flow, click "Uploaded Files" tab and click vfs_path to download the file or, click the Notebook tab and click Download JSON or Download CSV buttons to download JSON or CSV respectively, underscores are appended to beginning and end of filenames.

NOT to remove personal data? Does it give you an option for personal date not to be removed?? what about all the stored password? Can one of you tell me why all of sudden I get this error COULDN'T LOAD XPCOM? can you send me a link where to reinstall new version on top of the one I have running now Thanks

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

After installing Firefox on a new Windows 11 laptop, I've noticed some issues with the scroll bar. If I'm trying to view comments on Medium, for example, I am unable to scroll in the comments window as the main page scroll bar blocks it. I did not have this issue with Firefox on my previous Windows 11 laptop. I've tried changing some settings to see if it makes any difference with no success. I found a previous question regarding a similar issue where someone replied with a suggestion to toggle the "Always show scrollbar" option in the General > Browsing settings, however this option does not exist in my settings.

As seen in the attached screenshot, both scroll bars sometimes appear at the same time. However hovering the mouse over them activates the main windows scrollbar, making it impossible to scroll in the comments window. Trying to scroll the comments window with the keyboard arrow keys also does nothing.

I would really appreciate some advice on how I can fix this!

Hi

This has only recently happened but PDF comments are no longer displaying in OWA365 when using Firefox. I can open the same email in Edge and they are displayed fine. Strangely, if I go to print the PDF within Firefox, I can see the comments.

I've set my Application to open PDF with Adobe Acrobat Reader but this makes no difference. Is there anything else I can try?

I am a web dev and have a user download link to an excel xlsx file. On my own system it downloads fine in Chrome but in firefox ot displays the raw contents. Is this a FF setting?

Hello,

When I open Firefox, it seems like it does not does anything, but then it starts playing a music I was hearing in youtube earlier (like it seems to me that the window is opened somewhere outside of my screen??

If I click a second time in Firefox, then it opens a normal window in my screen as usual, but the other one keeps playing in the back.

I've tried changing screen resolutions, checked that no other monitors were detected, restarted computer,

Not sure what to do next!

Thanks!

I want help to recover bookmarks and password saved on my Firefox browser.

There was a issue with my Windows 11, due to which I was not able to boot on to Windows, hence I don't have the option to export the profile etc. Due to this the only option for me was to copy all the data on C drive through cmd prompt. After having taken all data back, I have reinstalled windows and firefox.

I did some search on the internet to locate the profile files so that I can get back my bookmarks and passwords. However I am unable to locate the same.

Request some guidance and help on this.

thanks Nitin

Firefox does not retain email login addresses for Fastmail email webpage.

I have used Firefox and Fastmail for many years and this has never been a problem. When I opened Fastmail previously and placed my curser on the email address box I was always presented with a choice of three or four email addresses. However now I am only presented with the first email address I entered since the Fastmail/Firefox upgrades.

I have contacted Fastmail about this and they suggested it might be a Firefox issue

Firefox will not run on my desktop as it says its already running. I have uninstalled Firefox & reinstalled it with a fresh copy from the web but the problem persists. I open Task Manager & see Mozilla Firefox appears to be running: "Mozilla Firefox (3)". I end task which stops Firefox opening further but the same thing happens again when I try to open Firefox.

My PC is running Windows 11 fully updated as at today.

Can anyone suggest a fix?

I don't know what happened, I haven't been tinkering with anything. This happens for every video, not just this one. I've also posted my addons as well, in case that helps with anything.

Please help me.

I made no changes to Firefox. It just stopped working. If I click on the icon I get a momentary hour glass, the hour glass goes away, and Firefox never comes up.

If I try to open it as administrator, it comes up but will not accept any web addresses. I can type in a web address but is doesn't go to the site. The screen just stares at me and does nothing.

Both Edge and Chrome work just fine. I have used Firefox for many years. I love it but has just stopped working. I have reinstalled it several times and the same problem occurs.

Using windows 11 on a desktop PC. Firefox has been my default browser for decades...issues have been very rare. But this is a catastrophic problem. One of those folders contains links to equipment mfrs, the other one has links to dealers and retailers. In the last month TWO folders and all their contents have vanished from my bookmarks sidebar and cannot be found anywhere on my computer. I NEED those folders...Where did they go and how do I recover them ?????

Help to do that will be appreciated!

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

So I've recently shifted from Chrome to Firefox and there's his specific touch pad gesture I set up on windows settings and it acts like media controls, but it seem to be unresponsive. Tried it with Chrome and VLC media player and it worked normally. Tried setting about:config; media.hardwaremediakeys.enabled but its already set to true.
