Firefox Community Forum

I have pop up blockers set to allow pop up blockers, but ev en though they are turned on. Firefox will not allow pop up windows in the learning management software (D2L brightspace) used at my university.

Two questions .......... You have my operating system as windows 10, it is windows 11 ??? ......... 2nd question ......... when I bring up Firefox it shows the weather for Chicago, I live in Minneapolis/St. Paul area, following your weather location change instruction, the weather still goes back to Chicago.

Dear Community,

the userChrome.css I used to use to disable the search bar expansion on focus no longer works (http://userchrome.wesleybranton.com/megabar). I disabled all urlbar.search options in about:config. But Firefox still gives me suggestions when I start typing about (as in about:config).

toolkit.legacyUserProfileCustomizations.stylesheets is set to true. The userChrome.css is inside the chrome folder inside the profile directory. I'm on 140.3.1esr (64-bit).

How do I disable this for good?

Thanks in advance!

Hi, thank you for reading this :) Since a week or two I have issues with drops in framerate of videos. It happened first on youtube but since then also on other platforms with other video players.

I've tried troubleshooting mode, fresh install, different network. Nothing helps. Speedtest has me at 160 mbps up and down.

The audio runs smoothly in all this though, it really is just the video that drops.

I use firefox on a Macbook and have this feeling it started to happen when I upgraded to macOS Tahoe.

Thanks for any insight!

Been trying to retrieved misplaced bookmark folders not bookmarks themselves in the Bookmarks Library with no success even going down several sub-levels; Would be nice if there were a search function, but will take a step-by-step solution. Thanks!

As per the topic, since the MacOS 26.0.1 update Firefox freezes after resuming from sleep. Specifically, tab selection, page refreshes or menu selections cannot occur. Keyboard command to quit does work and after a reload all tabs, windows and function is restored

None of my extensions have changed and for the first week or so after the initial MacOS 26 release this issue wasn't occurring. No other application or system changes have occurred since 26.0.1.

It only happens on some websites (Wikipedia for one) and doesn't happen anywhere else in my system. I was unable to root out the reason for this and all solutions seem to be for when there are boxes instead. I don't see boxes, only Russian letters for some reason.

Not sure when I download Firefox to new PC ,How do settings I currently have in place transfer to new browser installation?

Also I have bookmarks on a memory card,Will they install to firefox by placing it in drive slot of my new windows11 machine?

All of a sudden Firfox changed to an unrecognizable language + alphabet. I uninstalled + reinstalled Firefox 2 more times + the same thing happened. If I try to change settings, everything is in illegible.

I was updated to 143.0.4 a couple of days ago. Ever since, I've had all kinds of issues. Some sites won't load properly. Some links are not clickable. We're talking sites I use all the time and have never seen this happen before. I have not changed anything in my firewall or antivirus and have used them for years with Firefox. I refreshed and nothing. I actually uninstalled Firefox, cleaned out the registry entries, and installed 143.0.3 today. And yes, I did set it to not auto-update. Still misbehaving. I don't know if I missed a reg key that might be the culprit. I'm currently using Chrome Canary - although it's not my favorite, it is working normally on the same sites I've tried with Firefox. I even opened Edge for the first time in ages - it's working fine as well! I love Firefox, but I don't know what to do at this point! Please, can you help?
