Firefox Community Forum

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

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?

when i go to a site using firefox i get this message:

Secure Connection Failed

When I put my laptop to sleep, websites I am logged into are often logged out when I return. Note that I don't close Firefox. The tabs generally reopen but require login again. Windows 11, Firefox 137.0.1

For example, I put my laptop to sleep for lunch. When I returned, tabs were there, but I was logged out of gmail, Discord, and a website I was logged into.

This seems to happen more frequently recently, but not every time, as far as I know. But this is a relatively new problem, possibly related to a new laptop. Occasionally I get a message that there is trouble restoring my session.

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

suddenly my work account at https://outlook.live.com is a completely white screen.

access to other instances of this account (Onedrive, filesharing etc) are fine. Email account works on phone, so no problem with log-in

I have re-started the browser

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

The proxy settings just don't apply. I set the settings on the system, all programs work via proxy except Firefox (set to use system proxy settings). If I set the proxy manually in Firefox, the connection still doesn't go through the proxy.

I found that only the very first connection after starting Firefox goes through the proxy, absolutely all subsequent connections do not go through the proxy.

Hello, I am now seeing a problem displaying an Iframe with Firefox Browser 137.0.1 (64-bit). It appears but in a reduced form (about ten lines of a spreadsheet) without occupying the entire size of the Iframe. This problem did not exist previously in previous versions of Firefox. Please let me know if there is a solution. Other browsers display this Iframe correctly.

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

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

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

I am currently running Firefox Browser it shows Firefox is up to date and is running 137.0.1 (64-bit) About Firefox info screenshot is attached

Thank you, Paul Giler [email removed]@cox.net

i share my computer and when someone else uses the browser they see the last page I used. Emails open and they can see my private emails. how do I stop this without erasing history everytime I use it

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

Some of my bookmarks are gone AGAIN. This time adding .old to files and deleting others did not fix the problem, nor has restarting firefox. I can see that sites have blue stars, indicating that they are saved into bookmarks (such as "weather") that I can no longer see in my bookmarks menu. Trying to recover bookmarks does not work. I can see recent dates of bookmarks. I can see old firefox data on my desktop.

Bookmarks are a basic function of browsers. This is RIDICULOUS. Please fix this issue.

I have not had ANY UPDATES to my computer since yesterday. Yesterday all my bookmarks were there!

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

Since April 5th I have lost spell check in the message pane of the emails I type on outlook.live.com It still works in the subject line, but not the message area.

Windows 10 pro 22H2 updated to end of March, when spell check was still working well. Firefox 137.1 English Canada Language selected (has worked well for years)

I go to outlook.live.com to read and answer my @hotmail.com emails.

When right clicking on a misspelled word in the message area I get only these options, Firefox does not give me the usual options.

I am currently having other problems on that site, clearing outlook.live.com cookies does not clear the problems.
