I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?

recently I had my windows 10 reinstalled and had to reinstall firefox before the reinstate of operating system I had a video add on for facebook that would let me save a video to my desktop so i can send to facebook or send privately in facebook chat> had an add on that did that but i can not find it anywhere. again i had forgotten the name i think it was browser downloader but not sure. I forgot the name but loved it also now after reinstalling fire fox in the setting where it says application and defaults i do not see my mp4 which is windows media player listed there. I am sending a screen shot to you

Firefox Freeze after today's update when attaching files on Gmail. Crashed multiple times HELP !!!

Attachment window opens on Firefox program files

Then as you search for your file the attachment window , it freezes the entire browser.

Its not really a migration question but can be helpful to those who wish to mange their stuff without the use of other people's computers(the cloud).

I would like to turn all my addons into a text or html file of links or names. Why? The addons are going wonky again a few folders seem to be walmare but not reporting to be malware, its a huge pita to , manually write down each one. Basically, I need to nuke my install and reinstall it all fresh then reinstall all my addons. This is no easy feat when you use 20+ addons. And yes this seems to happen regularly after a couple of years.

Another question, If I sync'd just the addons would it let give me the addons fresh from the file repository without anything extra folders/files or will it just save my current addon folder corrupt files and all?

Also if I just synced addons it won't mess with my bookmarks or settings, will it?

Several months back, for some unfathomable reason, you eliminated GoodSearch as one of the eligible default search engines users can select. Given its squeaky-clean reputation and charitable nature, I can't for the life of me understand WHY. And just how much begging and grovelling will it take to persuade you to restore it to the available options?? *P*L*E*A*S*E*!!!!!!!

P.S. Making this contact form so damned hard to find isn't exactly endearing, either.

Since installing v100 I have had problems where tabs will not load anything. They will work fine for anything from 5 minutes, to an hour, then randomly just seem to hang. The only way to fix it is to close firefox and restart it, which is a PITA if you are trying to research stuff with multiple tabs and so on.

Additionally, some customers I support started getting SSL_Error_Bad_Mac_Alert errors... only on Firefox, and only when accessing google, and even then it might work fine for half a day, then continuously get that error- but open same page with chrome, and its fine. PCs on the same LAN also running firefox also had no issues with google at the same time as one of the effected PCs, but once updated also started getting the error intermittently (but again still not necessarily at the same time as each other). As you can imagine google is used a lot, and so this can be particularly painful. I have tried most of the suggested fixes for that error, and prior to the upgrade there were no issues.

Issue has occurred on both Windows 10 Pro, and Windows 11 Pro

Is there a way I can roll back one or two versions? It is really starting to become disruptive, and if it continues we will have to look at changing the deployed browsers completely.

Any time I visit a google page that has a map anywhere on it the page goes into a continual loop of refreshing until the google security page opens to make sure I am not a robot. When I click the captcha it reloads the page and the loop starts again. So then I entered about:config to turn autorefresh to false but it still does not stop the google page from a continual reload loop. What else can I do?

I am currently encountering a deeply frustrating issue with Firefox. I develop video games; I am attempting to download a zip file from Steam Workshop containing a player-created mod. I have this file on my other computer--it is not malicious. It contains nothing more than XML files and a jpg. Every time I attempt to download this file using Firefox, Firefox blocks the download as a potential security risk. I then click the download manager and tell it to download anyway; Firefox then pretends to complete the download, but in actuality the file remains at 0 bytes and a "part" file is created containing what I can only assume is the actual data.

Recently YouTube videos have stopped playing when I'm using the Firefox browser on Windows 10. This has occurred both on my laptop and on my desktop computer. The player, surrounding website, comments, description, etc. all load correctly. The video does not, instead displaying either the video's thumbnail and a buffering symbol, or a blank black screen and a buffering symbol. The time codes on the video load correctly. Ads do not play either, and instead after about 15-30 seconds of buffering the "skip ad" button appears in the lower right hand corner of the video. Videos play normally on both Chrome and Edge, and all other media content appears to load correctly (music/spotify, videos on social media websites, etc.)

So far I have tried: - Running Firefox in troubleshoot mode - Refreshing Firefox - Clearing the cache - Disabling and re-enabling hardware acceleration (didn't work either way) - Uninstalling and reinstalling Firefox - Rebooting my machine - Waiting for the problem to fix itself (it's been two weeks on my main desktop/tower and it's still not working).

At this point the only thing I haven't tried is messing with advanced config settings, and I'm avoiding that since I have no idea what any of them actually do (despite what certain reddit threads recommend).

As far as I'm aware, no specific update to either of my machines or Firefox has preceded the issue appearing. It's been going on on my desktop computer for about two weeks, the problem just started on my laptop last night.

It's worth nothing that I usually use UBlock Origin, Simple Tab Groups, and Facebook container. Those extensions are not currently installed since I had to reset my browser in the process of trying to fix the issue.

I can also confirm it's not an internet issue; speed tests show normal download/upload speeds for my wifi, and those have not varied since the issue began. All of my drivers are also currently up to date.

I keep getting this Problem Loading Page message:

Error code: SSL_ERROR_BAD_MAC_ALERT

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

    I've been through the Security settings and can't seem to find a fix. This seems to have started with the last update...

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again?

I have several windows open, each with different type tabs--i.e., dancing, gardening, etc. How do I save these windows so I can open them when I wish? I don't need them all open at the same time and having them all open uses up too many resources. Thanks in advance, Elizabeth
