Firefox supportforum

I turned my computer on; Mozilla wanted to update, so I said yes. Then I got this:

XUL Runner Error: Platform version '120.0.1' is not compatible with minVersion>=120.0 maxVersion<=120.0

And now I have no Mozilla. Restarting the computer didn't help. How do I get the old version back? I really absolutely must have all my bookmarks back....I use them for work!

How do I stop firefox from automatically downloading files from the internet when I click on them - without even asking me if I want to download them in the first place. In "Applications", selecting "Always Ask" in "Choose how firefox handles files etc" does not work. Firefox never asks. If it cannot be disabled, I will have to stop using Firefox.

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

My firefox just crashed and despite having sync active, saved ZERO of my dozens of tabs. in restarting, i see that despite sync still "on", it is only syncing a handful of tabs, and doesn't even update when i do so manually. am on a windows machine, but use firefox on two of these in addition to android.

will be switching to brave full time without Mozilla's help here.

thanks, z

Greetings,

My Firefox keeps crashing randomly even though it's a new PC with very capable good hardware. My old laptop used to run 100s of tabs without any issues.

However, on this new PC, the crashes are fucked even though I barely have about 20 tabs open.

Here are some crashing reports:

Kindly help. Thank you.

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

Yesterday on my linux computer I noticed that my container setup ise back to the default setting. Now I'm using my windows laptop, and it is als back to the defaults. I'm afraid the same thing will happen when I start using my windows desktop. Should I poll the network cable and delete my firefox sync data, so I can hopefully save my containers setup? Or is this not going to help, and I'm fucked anyway :)

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

Hello

Just to report Firefox 121.0.1 (64-bit) unable to upload any video formats on youtube and always having invalid video format error. I'm unable to upload even that videos what was already successfully uploaded some times ago. I using Microsoft Edge now to upload on youtube and it is fine with all my videos. Hope you can fix soon.

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

I recently upgraded from Window 7 to windows 10. Ever since, the spacing between the bookmarks has significantly increased. I read several post about this and they all seem to be looking for something in Firefox. I think it has to do with something in windows 10, not Firefox. Any ideas? I've already done the Density/Compact thing. Slight improvement, but not anything like it was under Window 7.

Yesterday I was playing videos on rumble fine. Sat my laptop down, picked it back up after waking up and suddenly no sound on any rumble.com video. Youtube plays video and audio fine. So does X and truth social. In fact, any website plays audio EXCEPT rumble.com. Its not Windows related. Its firefox related. I installed Chrome and rumble.com plays with sound fine. I uninstalled firefox and reinstalled and that didnt fix it. I have rumble installed via WebCatalog an it plays videos and audio fine. I then installed Firefox nightly and never signed in or anything and still rumble isnt playing sound. Its rumble+firefox=no sound. And it appears to be happening to others too on other help forums. DOES ANYONE KNOW HOW TO FIX THIS?

I've written about this before and never got a working answer. I have to use Chrome or internet explorer for some work because FireFox won't open the sites. This problem hasn't been fixed by I clearing cache and cookies as recommended back when I first asked a year or so ago.

Now the latest website I haven't been able to use is the Post office! USPS.com -- If I try to track a mail piece using my tracking number the site can't bring it up. The site tries for long time then tells me to try later. When I try with another browser such as Chrome, the result is there within a couple of seconds. It looks like I'm going to have to leave FireFox which I hate as I've used it so long - over ten years at least.

Version 121 Windows 10

Getting to www.costco.ca impossible during past few days - disabling tracking does nothing! Tried relaxing most security and tracking settings, still no results. MS Edge works just fine, like Firefox used to until now. Guess it's time to switch if no other option.

previously FireFox was able to login Spotify normally, and was able to post comments on Reddit, but suddenly it lost both abilities, and with the extreme lag on other sites, although still functional, i can't understand why these both sites can't be logged into, or can't post any comments in them. it has been this case for the past month. so what's going on? i'm NOT going back to Chromium based browsers ever again! i am in FireFox for a permanent replacement!

thanks in advance.
