Running Firefox 140.8.0esr (64-bit) on Windows 10 Pro on an HP laptop. The feature/problem described works properly with Chrome and Edge. The problem occurs when accessing the following article:

If the window is set wide enough, there is a sidebar displaying, "Share this content in X". If the screen is squeezed down (i.e. drag the right margin to the left) far enough, the sidebar will disappear. That feature is handled properly, but as the window width is increased and the sidebar appears, the main body of text does not wrap properly. It appears that Firefox is not compensating for the width of the sidebar.

A few weeks ago, I started to get repeated messages from Firefox asking me to make Firefox my default browser. Firefox has been my default browser for years, and I have never made anything else my default browser. Anyway, I followed the prompts and re-selected Firefox as my default browser. A little while would go by (sometimes as little as a minute) and I would again get the prompts to select Firefox as my default browser. This append 20 or 30 times. And, every time it happened, all of my saved passwords disappeared, but would reappear when I re-selected Firefox. In the last week, this situation has gotten a lot worse. Now, the saved passwords don't come back. And, the prompt you usually get when entering passwords to a new site offering to save the password doesn't appear any more. So, the only way I can rebuild my saved passwords is to enter them manually, which I am not going to do because it would take a couple of hours and then I'm pretty sure they would all disappear again. Also, I like to go to my homepage when I open a new tab. Can't do that anymore. When I open a new tab, I get a new private browsing window. I have checked all my settings a dozen times, and they are correct. I have combed your support sites and there is nothing there to help me. I don't want to dump Firefox, but I cannot continue with it behaving as it does now. Is there anyone anywhere in your organization who can help me? Thank you.

So i restarted macbook and when i opened Firefox, my bookmarks were all gone. i read the text about how to restore them but it didnt work and i really need those bookmarks. also i cant add bookmarks, its just not working. hopefully you'll help me with my question, thabk you.

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).

Latest version of Firefox on macOS, Mac Mini M2 - 8 GB RAM and MacBook Air M3 - 16 GB RAM: Firefox malfunctions on launch - I have to force quit and relaunch it - Firefox starts to load then freezes. Firefox works, then I launch other applications like Chrome, Thunderbird, etc. Firefox freezes on the M2 8GB RAM but rarely on the M3 16GB. A few weeks ago, these problems didn't exist on either of my Macs - since an automatic update that I didn't notice, it's now a consistent occurrence.

I like to default to having threading on. It used to be that when I opened my Inbox, every email thread was closed/collapsed. Now they're open (started somewhat recently).

I can get numerous separate emails where each one can generate lots of responses, meaning they threads get long, sometimes within a few minutes or hours. Having them closed by default (rather than open or unthreaded) makes it to see each individual email chain and other interspersed single emails.

I tried google searching; also tried threaded and grouped by sort (with the default sort set to thread), and it doesn't seem to help. Any help would be appreciated!

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

I have Firefox installed on multiple devices and most/all of them don't keep sessions or browsing history

I noticed that these files are updated while browser is open and get deleted once browser is closed:

• sessionstore-backups/recovery.baklz4
• sessionstore-backups/recovery.jsonlz4

No other files are related to sessions

I have "Open previous windows and tabs" checked

Installations:

• Windows 10
• Debian 12
• Debian 13 (Firefox 148.0 Snap)

On Firefox for Android, this issue doesn't happen, I can even see the whole browsing history including history lost on PC installations

In February this year I started having an issue with reading pdf formatted statements from my bank' (bank and personal information removed). Initially I thought it was some change at the bank so I sent the letter below to my bank.

Further experimenting with Microsoft Edge and Firefox leads me to believe the issue may be with recent changes to firefox. The attached jpg file shows the problem, though not a solution.

I would be curious to know if there is some (new) setting in Firefox to correct the problem.

Text of letter to bank:

re: document access on site

You have evidently made some changes in your account display and I have to tell you there are issues with it.

Previously the account document came up as PDF. Today I accessed the current statement and immediately noticed the change in display format.

I usually do two things here. First I print the document. The print button worked as expected. Next I SAVE a copy for future reference. The download button DID NOT WORK.

I had to use the print save to file function. This is where I found the problem. I saw this when I checked my print queue as well. Instead of PDF the document is now PDF.js viewer.

I have to ask why you went to java script when the original PDF format worked properly every time?

On the plus side, my pdf viewer still reads the saved file. It is the unnecessary print to file step to which I object.

I am not at all happy with this change and would encourage you to return to the previous process. Since it was NOT BROKE I am at a lost to understand WHY YOU FIXED IT.

I noted, that credit cards autofill works, but on ~50% of websites it fails. I can see the autofill dropdown, but if I select any card, no fields are filled. Manual filling works. One of examples: https://ipn.paymentus.com, but there are many. Again, on some websites it works just fine.

Another issue - I cannot edit cards. Settings->Payment methods->Manage, then select a card, press "Edit" and nothing happens.

Context: version 148.0 (64-bit), Canonical snap build (crap, I cannot DISABLE snap build and totally switch to deb!!!)

P.S. I really miss feature to add "aliases" for cards...

Thank you for the help! I'm wondering if other AI chatbots, Lumo, in particular, will continue to be added as options to the updated sidebar? An unofficial extension exists (https://codeberg.org/daskashk/lumo_ai_by_proton_chat_in_sidebar) that adds the ability for a link to appear in the sidebar. However, it does not offer the full integration that the official browser update provides to the other supported LLMs. I like Lumo for its privacy, encryption, and the ability to make "Projects." Thanks again for the help.

UNBELIEVABLE, I've never had this much trouble with a previous update. Your AUTOMATIC update closed all web pages that were open last session, offers no option to restore previous session, and took me 2 hours just to get bookmarks back. I had way too many pages open, but I have lost some important research for work that was in process. Multiple support options didn't work until I found one that would for bookmarks, but the history seems to be unretrievable. Not how i wanted to spend my morning.
