Diễn đàn hỗ trợ Firefox

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

So I have never had a problem with YouTube up until yesterday, anytime I try to watch a video and click play or anywhere on the video it just has a circle that spins in the middle around a youtube button, or sometimes just a black screen.

I have tried clearing Cookies & Cache, tried in safe mode, tried with a new profile, disabled hardware acceleration, I even uninstalled and re-installed Firefox.

Still for some reason I am unable to watch videos and only on Firefox, it works fine in Chrome and Edge browsers.

I am at a loss on how to fix this, and I really don't want to have to use two browsers for watching videos and navigating the internet.

Any Ideas?

Also my Internet is not the problem, I have Gigabit Fiber.

I have a problem with buttons in google docs, buttons works but pictures of buttons are dissipated. I asked about this questions to the community, but nobody could help me. I can't find if I can to get help from technical specialists of mozilla company? Is there only this community? This is really huge problem for me, because I work a lot with google docs and if I don't solve this problem then I'll have to go to another browser, but I don't want to :(

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

Hi, I'm trying to run and use Firefox as my default browser on Windows 11, but I'm running into some issues. The device is managed by Microsoft Family, which blocks Firefox by default. I got around this by renaming "firefox.exe" to something else. This works to get Firefox open, but the modified filename is causing Windows to not recognize it as a browser. As a result, I can't get Firefox set as the default for http/https.

I've tried tools like SetDefaultBrowser from Christoph Kolbicz but no success, it is unable to notice that firefox no longer exists as "C:\Program Files\Mozilla Firefox\firefox.exe"

Anyone have any advice on how to fix this? Windows seems adamant not to let me set the http/https protocols to anything it doesn't think is a browser (i.e. my Firefox installation).

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

Hi I put "about:support" in the URL field. The pressed "Open folder" button on the profile folder section on the troubleshooting page, then I got an error: "Location is not available." I looked for the folder, but I could not. "about:support" describes the location "C:\Users\xxx\AppData\Roaming\Mozilla\Firefox\Profiles\forv3n79.default-release but the Roamig folder does not contain "Mozzilla" folder and the subdirectories.

I want to take the backup as the purpose.

I suppose this is a bug. So, could you fix it?

Thanks, G

I got this issue when tried to read some API document provided by a marketplace that i have project with. I tried on another browser and it shown normal, not a single text is overlapping. I've tried some suggestion on another topic to pick No Style on Page Style menu (View -> Page Style -> No Style) but it got more messed up and tried changing font size but still got no improvement. Helpp me pls~

i just last night switched to Firefox and i am loving it! the only issue i have is that YouTube does not seem to be able to go over 480p no other website has this issue (for ex twitch) and if this could be fixed i would never go back to chrome

After upgrading to Firefox 99, Sharepoint will no longer load. The site can be loaded in all other browsers. After cache and cookies are cleared the page(s) work properly for a few clicks, but if you click the back arrow it goes back to the 3 Sharepoint dots icon and never loads the page.

Using Firefox on desktop, Windows 11. I am a long term Firefox fan/user.

My problem is I cannot find anywhere an easy method to add a shortcut on my Home Screen (which has now been a FF feature for some considerable time).

I am sure there was something available to do this in a prior version some time back. If I search the internet, I only come across articles describing how to do it on Firefox Android.

I know I can manually edit a box on the Home Screen to create what I need.

Sometimes new web sites that I visit appear in the boxes and I can then pin them in place - but the behavior around this is very erratic and unreliable - seems like random chance for an icon to appear on the home screen for a newly visited site. If this was more consistent, I could work with that.

BUT - where is the **intuitive** option??!!

I should be able to right-click on a tab and select "Add to Home Screen".

As simple as that.

Or drag and drop a link, or tab to the home screen - but this just opens the link. I have tried everything obvious that I can think of.

Anyone?

Many thanks :)

I've been using Dashlane for a long while. It stopped working, so I deleted it to try to solve the problem. When I tried to re-install it, it won't work. I just keep getting an error about it being corrupted. I've restarted the computer, closed Firefox. It's the same. Dashlane tried to trouble shoot with me, but they have not solved it either. It worked on Google Chrome, but I cannot get it to work on Firefox. Firefox is my browser! I need help to get Dashlane installed and working on it.

Firefox version 106.0.1 Windows 11pro. Youtube videos will not play, unless they are Live. Weird. Checked internet. Loads on phone, loads fine in Edge. Restarted FF, cleared cache and cookies, tried private browsing, started in troubleshoot mode with no addons-- even the ad video at the top won't play. What else am I missing? Why will the live videos play but not the others? That seems like a clue, but I've hit the end of my ideas. I was able to watch youtube two days ago, the only change (afaik) is a Firefox update this morning.

I must've accidentally pressed a button last night while I was watching a YouTube video on my desktop, as now the right and bottom edges are cut off when the video is in standard mode. Refreshing hasn't fixed the issue, neither has restarting or shutting down my laptop, as it was turned off for 12+ hours and I still had the issue when using YouTube today. It's even an issue in incognito mode, but not an issue if I use a completely different browser. I can't find anything else that has been affected by whatever button I must have pushed. Laptop is a Dell G15, if that's relevant. Would love any tips to fix this.

I have firefox set up so that it does not suggest anything except for my bookmarks.

So when I type in the address bar the only suggestions that come up are my bookmarks, no other suggestions.

For example when I need to translate something quick and want to go to the bookmarked page for google translate as soon as I type "trans..." it will suggest the link, Which is what I want and expect and is efficient.

But as has happened before, now I get a random suggestion coming up first so I have type more just to get to the same result otherwise I end up following a link to a suggested site which is at best aggravating.

I checked my seeting and there is one box ticked in the search suggestion settings that I cannot disable. I have tried and it always comes back.

How can I fix this?

Thanks in advance.

I recently upgraded to Windows 11, and was very careful, I thought, to back up my Firefox bookmarks and the tab plugin I use to save my sessions because for whatever reason Firefox can't handle that reliably. It all worked, because I could just sync it, but now a month later I had to reinstall Windows and... I can't sync my browser.

I've tried every password I could think of. I can't recall if I wrote it down somewhere last time, or changed it since, but I'm pretty sure I'm using the right email. Right now I'm logged in with another account.

And while I see a tab session saved from last month, which is unfortunately a little out of date but better than nothing, I don't see any saved bookmarks from this year. Just one from a year ago. I have no idea what's happened exactly, but I wasn't as careful this time because the sync worked so recently.

Now I'm stuck! I have some very important bookmark folders saved, that are key to all my projects basically. I can't just start fresh. But I can't log in, can't find any password change written down in my notes, which I may just have forgotten to note down. And I can't find any contact for Firefox support.

I do value security when it comes to handling my data but there must be a way to verify who I am, and change the password using my email?
