I'm having a problem using my bank website with Firefox - I get a message when I move from one page to another, and that message closes the bank website - Here is the message: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." It is very important to me to be able to view my accounts and investments daily - please help me solve this!

I wrote this on 13 June 2022: ...I am signed into a Firefox account. I have used this account on at least three different computers. I have downloaded the application anew at least a dozen times.

Firefox randomly, from where I sit, opens things in French rather than English. How can I keep it in English unless otherwise specified (I occasionally want German or Japanese)?

Thank you...

None of the suggestions worked. I reported that, but the thread was archived rather than answered.

How can I get all the info out of my account and try to start another that speaks English reliably?

Thank you.

New version produces "Access Denied" when logging into Chewy.com Please fix this. I tried to add an image, but, like last time, doing so froze the page and I couldn't get back here. Had to start over. Can I revert to the earlier version of Firefox that worked? If so, how?

Hello! When I try to log into my Microsoft 365 Outlooks, I get the following message:

'Your browser is a bit unusual...

Try disabling ad blockers and other extensions, enabling javascript, using a different web browser or turning off your VPN.'

I did go in and turn off the ad blocker. I do not have a VPN, and I could not find anything about Javascript on the Preferences page.

Please let me know what to do so I can log into my email.

Thank you! Christine

Every few days I get a notification that Firefox will be quitting in 120 minutes. However, there is no option to tell Firefox not to do this. I checked my settings and couldn't find anything about this either. My settings also say that my version of Firefox is up to date, so Firefox is not restarting for an update. Is this happening for other people? How do I tell Firefox not to quit without my permission?

Following a recent update (May 25th, 2023) I have lost all my notes. I know Mozilla does not monitor the Notes extension actively and the corresponding Github repo is archived (https://github.com/mozilla/notes).

Mozilla also notified the users about the decision to discontinue this service: https://support.mozilla.org/en-US/questions/1328311.

However, I found the "Notes add-on" useful, and kept using it. Finally with a sudden update in late May 2023, I have lost all my past notes. While searching for possible solutions for the data recovery, I came to find the following solution by " jscher2000".

1. https://support.mozilla.org/en-US/questions/1390845
2. https://support.mozilla.org/en-US/questions/1322197#answer-1384732

However, it was reported that though majority of the data was recovered by applying the technique above, lost notes were not among them: https://support.mozilla.org/en-US/questions/1390845#question-reply

For anyone with similar issue I am describing below what worked for me. Following the suggestion by "jscher2000" I first generated the "Old Firefox Data" folder on my desktop. This is how I did that: From the Firefox browser window, click on Help -> More Troubleshooting Information -> Refresh Firefox and follow the instructions.

After creating the "Old Firefox Data" folder you will be able to see one, or multiple, "profile folders" therein. On my system I was able to see multiple "profile folders".

Next, type "about:profiles" in the URL space of a Firefox browser. I saw only a single profile (the default profile) on my screen that followed. Next, you need to "create a new profile" and point the system to one of the "profile folders" inside "Old Firefox Data" folder. Lastly, hit the "Launch profile in a new browser". If you can not see your old notes, try with another profile folder inside "Old Firefox Data" folder.

This is what worked for me (Mac OS). If there is any better solution please suggest that.

I just went to one of my email folders in Googlemail and it was empty. When I began to check the other folders they are all empty as well, but on Google Chrome and on my phone all the messages are there. Why are they not there in Firefox? Can I get them back?

When I open emails many times the letters are gibberish. The letters are changed into symbols and weird looking letters. Sometimes closing Firefox and reopening helps, but usually I have to restart my computer. Even then, it may or may not be readable. Some emails are only partially this way, but most are complete gibberish. Has been happening for a few months. I have updated Firefox and am running the newest update. I am using Microsoft 365 email. Other computers in the same office do not have this issue. Any ideas how to fix this?

There is a bug when I try to make a video (Twitch, Youtube, ...) go full screen. I click in the full screen button and the video does not expand to the edges of the screen (the screen is shrunk slightly). There is a fix, but it requires the user to put the Firefox window in full screen and then put the video in full screen.

The other web browsers on my mac does not have this issue.

I searched for this issue and found one other reporting about this several years ago when quantum was first released - supposedly it was fixed. But it's still present here.

Firefox 113.0.2, MacOS Ventura 13.4

As the subject says, certificate exceptions added "permanently" in the Certificate Manager are dumped at various intervals. For example after updating to 113.02, my certificates for a local router and switch were gone. Sometimes the certificate exceptions seem to be removed at random intervals. Can't really nail down what causes this but the "permanent exception" is not honored. I added several certificates a few days ago, now they're gone.

This has been an ongoing PITA for the past year or more. Why does Firefox make this so difficult?
