I'm trying to install ad blocks and it seems that the Firefox browser doesn't recognize itself as a Firefox browser. It's telling me to download Firefox when I'm using a Firefox browser in the first place

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

Hi, so i have a question: what are your plans to support windows 10 after 2025? How about windows 10 iot ltsc which is supported until 2032? Will firefox still be supported after 2025 on the iot ltsc version? Or will i have to switch to linux?

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

Hi! I m trying to uninstall firefox in windows 11. The "installed applications" of windows doesn t appear. Then, when using helper.exe does not allow to select "uninstall". Simply reinstall the application. Any suggestion? Thanks

Like most people, the only reason I stick with this browser is for the ability to set it the way I want. Accepted the "upgrade" to 133 and it screwed my settings. Downgrading did not help. So fed up with this [redacted].

A problem with an x.0 version? I've been using FF from "source code" for years on Debian Linux, but this is the first time such an update is failing after the most recent update to v133.0, as illustrated in attached image. How can I now update to the fix for this problem, please?

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

Why is moZilla forcing me to use Google Play Store to download Firefox? I used to be able to go directly to mozilla and get it (and yes i'm talking also about the android version)

Hi, using Mac OS. Have tried the about:config set the auto update configs to false, still it keeps prompting every day or a few hours . There is also a timer setting. They dont seem to work, and these update notifications are very irritating, keep popping up every 8 hours or so.

Not sure the necessity for these incessive updates every day or hours, it uses a lot of system resources and hdd space, can Firefox put back the option when we can just tick 'update only when we want them' , in these, no background timer required they use system resources and there are many of us do not want them.

So I've been beating my head against the wall on this one... first I couldn't load Firefox and the error message would say 'Firefox is active but not responding.' I looked into that, it suggested deleting the profiles.ini file... I did, and it didn't do anything. I then tried deleting the profile folder entirely. That changed the error at least. Now it says 'no profile.'

So, I tried following directions to create a new profile. Win+R, firefox.exe -p and then tried to create a new profile and... nothing. "An unexpected error has prevented your changes from being saved."

Unsure if its connected, but at the same time, several Steam games have been struggling to sync to the cloud, and Discord stopped working to the point I needed a clean install.

Already tried to do a clean install with Firefox and that didn't work either.

Last night, my computer crashed while running Firefox and now whenever I try to run it, I get an error message that says "Couldn't load XPCOM" and the browser closes itself.

I've tried reinstalling Firefox multiple times through the uninstaller and by manually removing the files in Program Files and appdata, but I still get this error. If it helps, I also get this error when installing a fresh Firefox installation.

I hope I can get this solved soon because I have a ton of deadlines coming up for school and I'm not able to clock into my remote job, either... Any help is appreciated

Firefox updated to 113.0 and moved tabs to top, above the address bar and the bookmark toolbar is now on the bottom under the address bar ... Is there an updated CSS file I can copy that will restore bookmarks toolbar above the address bar and the tabs below the address bar? So the order would be: Menu Bar, Bookmarks Toolbar, Address Bar, then Tabs Bar? This really is hard to work with. Thanks!
