This happens on Firefox for Linux Mint 149.0 (64-bit) brand new profile.

This occurs when there are multiple tabs open to the point that they need to be resized after closing a tab.

When I attempt to close another tab with a middle click, all the tabs are resized on the mouse click down action. The tab that is newly under the cursor when middle click is released is closed. This is causing unintended tabs to be closed.

Any help or workaround would be appreciated.

Thanks, Tim

Hey, i am since 30. 03.2026 from windows 11 to linux mint changed, in firefox- browser amazon musik unlimited doesn`t work. But i have there all of my musik and i`ll missed it so. Is there no option to here my musik?

how to see how many time and when I visited a website in firefox. like I visited "https://www.themoviedb.org/person/500-tom-cruise" 10 times. now it only show latest time not the first or secnd or third in firefox. how to see?

Sorry folks, this is really confusing for me and it kind of snuck up on me like fading breaks on a car.

"This" computer is my main one and I use it the most.

I load youtube and get the usual list of suggestions. If I moved my mouse over any, they would start to play and I would "preview" them on that screen. I could select if I wanted the audio and subtitles.

All was good.

Fire fox has updated and the O/S has also over time and "recently" the "preview" stopped. (Oh well. Such is life.) I didn't think much of it.

Then the other day I was on ANOTHER machine (different O/S, similar/same plugins) and loaded youtube just for the sake of it and as I moved the mouse over the clips: I got the "preview".

I've shared the data from this machine. Kind of difficult to do it in/on THIS post from the OTHER machine also.

For clarity: It used to work. I didn't change any settings in any of the plugins/addons or FF settings. They were "working" as I wanted and so there was no reason to change them. I am guessing this is a "easy thing to fix" but the specifics of what I need to do is beyond me at this point.

I'd appreciate some guidance in how t find the difference between the two machine's settings so I can get the preview to work again.

Just to put it out there too: I have a "squillion" tabs open. They all seem to work and unless I really get carried away with things, Firefox 95% of the time behaves itself. Now and then it "locks up" and stops responding. The best solution is a total reboot and restart.

When I enable the firefox built-in vpn I have an error: "The proxy server is not found

Firefox cannot connect to the server at accounts.firefox.com What can you do?

Try to connect to another device. Check your modem or router. Log out and reconnect to Wi-Fi."

Thanks.

The Firefox default behaviour to reload a page for view-source even when it is already in memory is unnecessary and causes many difficulties when tracking CGI bugs.

This unnecessary reloading can be turned off by setting accessibility.blockautorefresh to true.

However, fixing these stupid page reloads this way introduces another hyper-annoying behaviour: then Firefox blocks redirects.

So this accessibility setting is bad in both possible settings. Is there a possibility to prevent reloading pages for view-source while still allowing redirects?

I had 6 groups in the sidebar showing when I closed Firefox last night. Today when I opened Firefox there was only one group showing how do I get the other groups re-displayed in the sidebar? I am finding no clues when using the last line in searching help

I set up firefox using my customised user.js, and I have been able to configure everything just as I want except for "Search Shortcuts".

Are there Firefox "preferences" (in the about:config "preferences" database) for the 10 or so "alternative search engine" entries (shown in about:preferences#search)? If not, is there any programmatic way that I can edit these "alternative search engine" entries so that I don't have to manually disable and/or remove them every time I install Firefox on a new machine?

TIA.

I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks
