In the last few days, Firefox has stopped remembering tabs that were open when re-opening following Windows re-boot or other closure. This is frustrating. Other browsers (Chrome and Edge) both remember all tabs/windows that were previously opened.

Why has this suddenly started happening and how can it be resolved? I have gone through the advice given 2 years ago on one similar question, and all the configurations are in order.

I keep a large number of tabs open but occasionally go through them and close the ones I'm no longer interested in (with the X next to the entry in the tab bar). However when I then close firefox and restart firefox they are all back in the tab bar. This is relatively new behavior, perhaps a few weeks.

How can I fix this.

firefox 131.0(32 bit) W10 (32 bit)

Is there a way I can go back to the previous version? This latest update has really slowed my computer in loading everything. It is very frustrating. This is not the first time an update has broken things.

I use Thunderbird Mail, I have two email accounts, a gmail and an icloud. Now a problem has occurred, all subfolders for icloud have disappeared from Thunderbird. I had different folders of saved correspondence, but now I just see Inbox, Archive and thrash. Anyone know what I can do to get those folders back, for gmail account everything is ok

I've been on Thunderbird for almost 20 years and a Mozilla fan. Have evolved a fairly elaborate configuration of local (POP) email folders, rules, calendar, and accounts to manage & organize email activity, retention, archiving, etc. I've not had to deal with Profiles in previous upgrades and don't have much experience with it.

The recent Oct 1 push of Firefox & Thunderbird 131.0 releases took me by surprise. I was able to re-implement the previous Firefox profile to recover bookmarks, cookies, passwords, etc. However, when T-Bird warned that 131.0 was Beta & unsupported I took the suggestion to download & install the current supported release: 128.3.0 (I was on 128.2.3). Then hell came.

Once downloaded, installed & launched, Thunderbird 128.3 cautioned the new profile created with T-Bird 131.0 was incompatible with previous versions and that I should create a new one, which I did. Still could not get new T-Bird to recognize previous profile, so I tried uninstalling, downloading & reinstalling 128.3 multiple times, each time prompted to create a new profile before proceeding. I tried to follow the previous profile restoration process detailed on support forums & articles, but none seemed specifically relevant to my situation.

I located my profiles in the appdata roaming profile folder, including what I think are most recent based on size of mail folders. Can't determine whether I had just one or several in use due to the extent of my setup. Could really use some help & advice to: 1) Determine which profile was in most recent use prior to T-Bird upgrade. 2) Whether more than one profile was in use. 3) Re-implement the profile I was using on T-Bird 128.2.3 with my new 128.3.0

Regards & many thanks in advance, John C Houston

PS You'll ask why I would upgrade to 131.0 from 128.2.3. Answer: it was on auto-update and 131.0 is what was pushed. No more auto-updates for this guy!

I have online accounts with both drawboard.com and offerup.com. Neither of these websites will finish logging out when I click log out on Firefox. I assume it's a Firefox issue as I do not have the same problem with Safari or Chrome when I've tried. I really don't want to stay logged in to those websites when I'm not using them. On Drawboard, the logout page just gets stuck there and won't change even if I refresh. On Offerup, it doesn't do anything at all.

Been trying to log out of offerup for weeks even with their help desk. Please help, thanks.

I have had two Gmail accounts on Tbird for about a year with no problems. Now I get unpredictable or no results trying to send or receive messages from the newer account. A message mentioning unsuccessful server authentification is the most common. "we have sent your message but not mentioned it in the "sent" folder due to connectivity problems" also occurs. I have absolutely no problem on iOS mail or Tbird running on MacOS. To the extent that I can decipher the iOS settings, there is no difference.

Today I was notified Firefox version 131.0 had been installed. Now, when using the Charles Schwab website, I can't access my bank account, which is a separate entity, and requires me to use Schwab's access method. I've used this method/tool for a decade or more without incident until FF 131.0 showed up. Here's the error: "You might have cookies blocked or cross-site tracking prevented. Depending on what browser you're using, check your settings for these terms: • Block third party cookies • Cookie tracking • Cross-site tracking Make sure cookies are not blocked and cross-site tracking is enabled.

I've disabled "Enhanced Tracking Protection", cleared the browser of cookies and site data. I disabled Privacy Badger and Ghostery. None of which helps.

This procedure works using Firefox on an ios tablet. Also, it works with Microsoft Edge.

Thanks for any help. -Deke

As the subject says Firefox very suddenly started giving me terrible loading times, despite all the sites working perfectly fine on other devices and browsers. Issue continued with troubleshooting mode, not sure where to go from here. I will open youtube, it won't load about 5 thumbnails, I click on a video and it sets it to 140p and then it still lags the entire video as if I was using 1kbps internet. I tested my wifi connection and its having no problems. Something similar happened when I used to use Opera GX, it was fine for a long time and then one day terrible performance. Please let me know where to go from here. Windows 11 Pro.

It seems a new version of Thunderbird was updated and installed today. Although the new message button seems to be working it looks like a dark black button. How can I change the color setting so it is readable?
