Firefox Community Forum

I updated Firefox to version 138 yesterday(29rd April). I use latest stable version of Linux Ubuntu. Sites itself will work, but top of browser wont. Can click open new tab from +-button, but can't close it.

Browser stops reacting to mouse clicks when browsing (after hours of browsing) and I have to use right-click to navigate on sites.... until I restart browser. I tried to close tab and refresh tab when these problems occurred. Also, this occurs on all sites.

I think this is clearly browser problem(because clicked areas are on browser, not inside tabs), not problem in sites itself, because problem manifested itself after hours of browsing, not immediately.

Edit: I'm not well-versed enough to write Bugzilla-report. Also in 138.0.1-1 version, where I updated 3rd May 2025.

Edit 2: I've added picture of area that stops working. Edit 3: On another picture, can't close "Archaeology" tab, no matter what. Edit 4: Clarified things up.

Hello

When attempting to pay for online purchases the new firefox upgrade (Mac 133.0.3) will not redirect from the merchant to the payment site. Yesterday, before the upgrade, was no problem making credit card purchases online; now, nothing. Please advise on how to set up new firefox version to allow redirect to payment websites from merchant sites.

Thank you.

Firefox version Mozilla Firefox 137.0.1 has caused my access to content.clubrunner.ca to stop working. How do I revert to version 137.0?

I'm unable to log into my social security account when using firefox. Have no trouble with safari.

I get the following when using firefox:

400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

I have had multiple sites ask me to disable my ad blocker. I can't find an ad blocker in my extensions. Badger, which I do have, says it is not an ad blocker! Some of these sites, such as Rotten Tomatoes, are sites I use frequently! Help!

Latest update 136.0.2 ruined all accesses like gmail, bank-sites, other (password) protected sites, even access to Firefox was not easy. Please fix issues back to previous 135 version.

All of a sudden, starting today, I cannot view video clips. IK get and error message "No video with supported format and MIME type found. Is there a way to fix this or do I have to reinstall my computer from scratch?

Hello developers;

I have used Firefox for long time on both Mac and Windows.

Recently, I have been experiencing the phenomenon described above, i.e., when entering Japanese text into iCloud Memo on Firefox, it appears as a double character. I'm sorry but I haven't taken screen shot.

This is the same on both Mac and Windows. It does not depend on the Japanese input method (IME). Refresh and reinstallation did not resolve the issue. Finally, I reverted to the previous version and the phenomenon was resolved.

From the above, we assume that the problem is caused by some kind of recovery in the latest version.

Thank you in advance for your confirmation and response.

12/12/24 - netflix says i need to upgrade firefox browser in order to watch vis, but running MOST current version (115.18.0esr). Mac OS 10.12.6 . need help fixing issue. thanks

On Windows 11 and a new computer, I ordered some items on Amazon yesterday. After that, I tried to log into my bank account but was blocked by "CloudFront," which appears to be used by AWS. I am not a member of AWS and do not know why this is happening. My bank told me it was "something in my computer," and that their website was up and running. On my older computer, I used Mozilla, and never encountered such a problem. I would appreciate directions and advice.

I was receiving duplicate diaglog in the GolfWRX forums such as member name showing twice. I cleared cookies and now the website only shows what looks like a table of content page, I see no details or graphics.

This issue seems to be getting worse as time goes on. I have to go to another browser to use Cabella's, Nextdoor, and several others. sometimes I get bad request when using a link or in the case of Cabela's I can not navigate their site. Lately I have been getting a warning of dangerous site when I hit the link in an email for all the forums that I belong to.

I love Firefox's bookmark system, other wise I would just use another browser, but I'm hoping you can correct these issues for me.

Thanks, Jim Roney (long time user)
