Whenever I click my mouse somewhere blank on a webpage firefox will always select some text/image despite being nowhere close to it. This does not happen to me on chrome.

I have Hulu live tv streaming and the video is not streaming. I get a black screen when I select a channel or an item from the library. This also happens when I try to stream local tv stations' 24 hr streaming sites. Other streaming services (Disney+, ESPN+, Netflix... etc) stream just fine. Hulu works perfectly in Microsoft Edge but I truly prefer not to use it. I've been using Firefox for years. This has happened after the latest update of Firefox. The update before this latest I experienced a similar problem and using the trouble shoot mode narrowed it down to a problem with Adblocker Ultimate extension. I deleted the extension and reinstalled it and the problem corrected. I did the same this time and no success. I have cleared the cache and reset Firefox and still the problem exists. TIAF any help.

Hi folks

Until about two or three days ago the www.bt.com website opened as usual, with first of all its cookie panel taking over the screen asking whether to accept cookies or manage cookies, and after handling that the site was perfectly usable.

As of two or three days now the cookie panel does not come up NOT AT ALL [but see also the last part of this message], and the screen is lightly-greyed-out. The screen scrolls but nothing at all is clickable.

However, in Chrome and Edge the site opens and works as expected.

The site also opens on the iPhone using both Safari and Firefox and works as expected.

It is just FF on my W10x64 Desktop where I have the unclickable lightly-greyed-out screen problem.

Perhaps something has chaged in FF, so I went into Settings-Privacy & Security- and then did the following:-

• Went to Site Data then "Manage Exceptions then I specifically typed in and Allowed the www.bt.com website

• Then went to Permissions and Block pop-up windows and in Exceptions I typed in and Allowed the www.bt.com website

• Then cleared FF cache

• Then reloaded FF

After all of this - no change; the www.bt.com screen is still in a lightly-greyed-out and unclickble, but still scrolls, however, after taking the above bulleted steps, the cookie panel now momentairily only flickers onto the screen and then disappears, and, sadly, the screen remains lightly-greyed-out and unusable.

Am I missing some sort of blocker for this website?

All other websites work on the Desktop PCs FF as expected. It is just this www.bt.com website that is the issue.

I have spent 30 mins with a BT Support Agent on the phone and we both agree that as Chrome, Edge and Safari are all fine it must be an issue with the Desktop version of FF.

Does anyone have any suggestions?

Thanks.

Captcha is not working. In fact, the widget is not loading on my computer on any browser. However, when viewing the console while loading the website, is gives the error messages shown in the image.

All extensions are disabled.

I am having trouble pinning any Extensions to my toolbar. When i click on the Extensions icon (puzzle piece), the Extensions menu immediately pops up. My extension (Bitwarden) is set to "Enabled". When I click on the three horizontal dots, however, the only options are 1) Remove, 2) Report, or 3) Manage. There's no option given to pin the extension.

Because of that, the extension basically never opens, and I am unable to use it. Does anyone have any suggestions for me? Thanks in advance.

I am running Firefox 129.0.2 (64-bit) in Windows 11 on a Surface tablet. FWIW, the extension is running fine in Chrome.

Hello! I have been having certain visual bugs occurring within the Firefox browser, I do not know what's causing them but am hoping someone can help! Firefox keeps on adding or changing translucent white boxes to multiple websites, I have some from YouTube attached below but I've had this issue on multiple websites. I'm using an ARM architecture Surface Pro X and when I reached out to Microsoft they couldn't help me since the error was just in Firefox.

There has to be a way, but I can't find it. How do we enlarge the font size for tabs, toolbar, favorites, search bar etc. I like that we can customize the colors but the font size seems to have been left out. I know we can ctrl + to enlarge what's in the browser window but this has no effect on the actual browser fonts. They are wayyyy to tiny. Is there a fix for this?

I've got a question/suggestion about Picture in Picture feature. Why "Close" button works the same as "Back to Tab"?

Scenario: Close the Picture in Picture video by clicking on the [X] button or Cmd+W shortcut.

Actual result: Picture in Picture closes and Firefox window opens, on the tab containing the video. This is very strange behaviour. If I close the video, I don't want to watch it now. Essentially "Close" button works exactly like "Back to Tab" button - so what's the point? If I wanted to switch to the tab - I would click on "Back to tab".

Expected result: I expect Picture in Picture video to close and nothing else to happen. Don't open the window/tab containing the video.

Thanks

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

PROBLEM: After a restart of Windows 10 and re-starting Firefox, a Firefox window with a YouTube web page in a tab will start playing unbidden. When multiple Firefox windows with multiple tabs each are in use multiple YouTube videos will start playing. (Only one of possibly multiple YouTube tabs per FireFox window, I believe.) The cacaphony is annoying. Tracking down the offending tabs is difficult. (There is no "Show tabs playing media" feature in Firefox.)

QUESTIONS: (1) How do I prevent Firefox from playing media (YouTube and others) unbidden when Firefox re-starts and re-loads its tabs? (2) How do I quickly find which Firefox windows have a tab that is playing media? (3) How do I quickly find which Firefox tabs are playing media? (4) How can YouTube videos be prevented from automatically starting when a Firefox web page with that video is re-loaded?

Hi there,

I'm new here so please bear with me if I've posted in the wrong place or have missed something obvious.

I running Windows 10, fully updated, on a laptop. I have been using Firefox browser now for many years, suits my needs and avoid's using Goolges Chrome. My Firefox was updated a in the last few days and it shows as up to date on Version 129.0.1 64bit.

I noticed late last night that when opening a fresh window and enter a search term in either the address bar or the Google search bar, my usual choice of search engine, I hit return and nothing happens. Any text I've input disappears totally. Not at all sure what's going on but have found that if I open a new private window Firefow will act as I'd expect without any issues.

I have two other browsers on my laptop, Edge and also Avast's own offering which both work as expected when I enter a search term. Have never experienced this before with the exception of years ago when malware protection wasn't great. It almost seems as though something is just stopping Firefox from searching anything I enter. I can use the bookmarks just fine and then everything works as usual.

Yesterday I thought that maybe following the new windows culmulative updates I was offered and apparently installed just fine, that I needed to restart which a tried and I thought it had cured the issue. Seems that it hasn't and still having the same issue.

Any idea's or thought's on what the cause of this is?

Hi, I get a message "No video with supported format and MIME type" when I try to watch movies on my website : https://www.spiriferminerals.com/product,25270,produkt.html The same movie works on Chrome but not on Firefox. Can you help ? Thanks ! Joanna

For about two months, video quality has been persistently low for me on Youtube. Quality options are limited to 360p and I am unable to change it. Additionally, I am unable to play video on other platforms such as Vimeo, Pinterest and other streaming sites. Sites return errors such as 'Player is unable to play video at this time' or error code 102630. I have refreshed my cache and reinstalled Firefox and neither have resolved the issue. Notably, this issue does not occur on other browsers such as Chrome or Microsoft Edge. As far as I know my drivers are up to date and the Windows Media Feature Pack is installed, although it shouldn't be an issue seeing as sites work on other browsers. The issue also persists in troubleshooting mode. I've gone through the console and included images of some interesting errors that might be of use, although I don't have the technical knowledge to know what they mean. Please inform me if there is any other information I can provide that would help. Thank you!

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

on PC A, firefox just lost all open tabs (even pinned ones), history (for this device only thank gods), open windows.

I installed a windows yesterday on a different PC (lets call it B), and logged in with the same microsoft account PC A uses. Then installed firefox and logged in to sync (on PC B).

Did that somehow overwrite the profile? Even though it was a different PC?

all my tabs from open session disappeared?!?!?

and no way to restore it; the option disappeared and I never erased it or close any of the tabs manually and it was on sync. Where did they all go ? I can see now the history from my laptop mixed with my mobile under the history tab but the session disappeared?!?!

Firefox use to be EXCEPTIONAL and 2 years ago it star5ed to go downward; please convince me to stay loyal and not switch to brave or opera; this is becoming worst every months.

I did everything I found with ChatGpt and nothing works:(## Recovering Lost Tabs in Firefox Android

I understand that all your open tabs in Firefox Android have disappeared, even though they are synced. Don't worry, there are ways to restore them and reopen that session on your mobile device.

• • Here are the steps to recover your lost tabs:**

• • 1. Check Recently Closed Tabs:**

• Open Firefox on your Android device.
• Tap the three dots menu in the top right corner.
• Select "History" from the menu.
• Choose "Recently Closed Tabs" from the History list.
• This will display a list of recently closed tabs. If you see the session you're looking for, tap on it to restore all the tabs.

• • 2. Use the "Restore Previous Session" Feature:**

• If the "Recently Closed Tabs" option doesn't work, try the "Restore Previous Session" feature.
• Open Firefox on your Android device.
• Tap and hold the "Home" button.
• A pop-up menu will appear. Select "Restore Previous Session".
• This will restore the last browsing session you had open, including all the tabs.

• • 3. Check Your Synced Devices:**

• If the above methods don't work, check if your lost tabs are open on another synced device.
• Open Firefox on your computer or another mobile device where you are logged in with the same Firefox account.
• Look for the lost tabs in the "History" or "Recently Closed Tabs" section.
• If you find them, you can open them on your Android device by syncing your browsing history.

• • 4. Contact Firefox Support:**

• If none of the above methods work, you can contact Firefox support for further assistance.
• You can reach them through their website: https://support.mozilla.org/en-US/products/firefox/fix-problems/
• Explain your situation and they will try to help you recover your lost tabs.

• • Additional Tips:**

• To prevent this from happening again, consider enabling the "Open Tabs in Background" setting in Firefox. This will keep your tabs open even if you close the app.
• You can also set Firefox to automatically restore your previous session when you open the app.

• • I hope this helps you recover your lost tabs and reopen your session on your mobile device.**); is there a way im missing ?

Only thing that happened is that I restared my phone earlier?!

So, I'm switching from Chrome and there's this one thing I can't seem to be able to replicate in firefox.

When I start my day I usually open several tabs from different pages of the same website. In Chrome, I would do that by: -typing the name of the website in my address bar -all the pages I frequently visited in that website show in my suggestions -I middlemouse-click all of them, one after the other -this opens one new tab for all of them -I then switch to those tabs and browse them

However, replicating this in firefox seems impossible. When middle-mouse-clicking the 1st link, I would have my window forcibly switch to it, not letting me open the other tabs without changing tabs again. Recently I learned I can avoid this forced switch by middle-mouse-clicking the URL on my address bar while holding shift, which is great! . . . Except it still closes my address bar, not letting me click the other ones without having to type the website's name in it again.

I don't mind holding shift (though I wish I didn't have to) but I really just want to middle mouse click multiple links in my address' suggestion bar and open them in succession, without shifting back to it after each time.
