A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

I need to install a browser on a Windows 7 laptop that I'm trying to get operational so the files / data can be migrated to another platform. I would like to use Firefox if possible.

I'm thinking I would need a prior version. If so, what version should I choose and where do I get it from?

The current / legacy browser is Brave but that has been disabled by installing Bitdefender as part of the ongoing cleanup process. --Thanks

"The WidevineCdm plugin has crashed" - unable to use any streaming service.

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

Greetings Firefox Support/CommunityL

While reconnecting one of my computers to my Firefox account I saw at the top of the Settings Page: "Your settings are being managed by your organization". Problem is that I don't belong to any organizations or enterprises having anything to do with my online life. I have been hacked in the past and am paranoid when I see something that doesn't make sense. When I click on the link (trusting that it is indeed from you), it takes me to your Enterprise Policy page showing the following:


Active Policy Name Policy Value

DNSOverHTTPS Enabled false Locked true

I always use secure DNS (DOH or DOT) on everything - network adapters, routers (except the ISP one whose default I can't figure out to circumvent) etc. but on the browser setting pages I am only given the option of having it off: the default, increased, and max protection options are greyed out and cannot be chosen. I guess that explains the policy values but who locked it? My only guess is that is use a Surfshark VPN and realize that in so doing I am using Surfshark's DNS servers but I believe I had this problem before using the VPN. Any help would be greatly appreciated. Thanx.

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

Not sure when it started but nearly every attempt to play Youtube videos results in the video freezing after about 1/2 second while audio continues, then the video jumps forward randomly before freezing again. Have reloaded, restarted, cleared history, cookies, etc, and nothing helps. Mean time Chrome plays the videos flawlessly. This is a recent problem with FF and needs fixing badly as it will just not go away.

Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Firefox 112.0 running on Windows 10 64-bit laptop with a small (pixel geometry) display screen has unnecessarily large padding (white space) around each bookmark as I navigate bookmarks on the bookmark bar.

I believe this was a change instituted around version 89 (in a nutshell, I could see more - twice as many? - bookmarks listed within a bookmark folder with version 88/before. The vertical whitespace between bookmarks within a folder is excessive and makes it much more necessary to scroll within a (long) list of bookmarks in a folder when looking for one.

There was a procedure posted in the discussion below on how to set and enable "compact density".

Bookmark Padding in New Firefox Versions 2 https://support.mozilla.org/en-US/questions/1369996

The procedure below was attempted - browser.compactmode.show enabled, browser restarted, however, I cannot fin "Customize Toolbar" and "compact".

"go to - about:config search - "browser.compactmode.show" - change to TRUE , then close that window go to - Customize Toolbar at the bottom of that page, there a box called Density. Click that, you'll see "compact (not supported)" Apparently, it IS supported because I chose that. (it looked like it ignored my choice) After I closed Customize Toolbar, the bookmarks were compact spaced again. Exactly how I need them."

Is this fixable/solvable?
