Diễn đàn hỗ trợ Firefox

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

This is both a settings issue, and a privacy and security issue. I want to disable the google lens context menu item to protect my security and privacy from constant AI monitoring. I've almost accidentally clicked the new option before and I don't want to send photos or images to google's AI unless I specifically intend to do so.

I feel like Mozilla is interfering with people's privacy more and more, taking away features from their users, adding features we don't want, butting in and telling us how our browsers should work. This is starting to become absurd. Now you've added AI into the browser that can control how your tabs are displayed and named even, a setting I found while trying to disable Google Lens.

There's a couple other settings I need to figure out how to disable too, such as the context menu of translate and the ChatGPT context menu items. I just removed ChatGPT and a new AI chat bot option appeared. Just wow. What the hell Mozilla. Is your intention to just turn your browser into one big spyware?

Give me the option to disable all of this stuff you keep adding. I have a policy thats supposed to disable your auto updates too but YOU disabled that as well allowing you to install all this malware/spyware into my machine without my authorization.

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

Hi, I have the settings of 'General > Startup > [checked] Open previous windows and tabs' on. Most of the time it works as expected, but there are several occurrences when all of the sudden all of my pinned tabs are gone. When this happened, I usually tried the 'Command + Shift + T' to restore them. Sometimes they came back, some other times, they don't.

Can you fix it?

It's starting to get really irritating because I can have >12 tabs pinned and it's troublesome to have to remember them all in case this happens again in the future.

Thanks!

Hi, when I want to zoom in to the website page, I cant seem to find the horizontal scroll, thus I cant see the left side of the page that I zoomed in. Please make the horizontal scroll available. Thank you.

Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.

Thank you for any help and feedbacks. --Rod

After my bitwarden add-on failed me, I remembered ChatGPT helping me with this another time - but I got it wrong. I right clicked the extensions button (I have 3 add-ons falling under that button) and removed from tool bar, thinking I could then reinstall it and the Bitwarden issue would rectify.

Instead, the extension icon disappeared, and is nowhere to be located. ChatGPT wants to do some reconfiguring but surely there's a better way. I have looked in "customise toolbar" (ie, right click toolbar, click customise toolbar and look for the icon" - but the puzzle piece icon is not there.

Surely I have hidden the puzzle piece icon somehow and I need to do some sort of magic to make it reappear... Have never had this issue with Firefox previously.

I have asked this question before and followed ALL recommendations to no avail. I received no other suggestions to now, nearly a year later I am asking this question again. I had to stop using my favorite browser because of this. You all used to help your users but alas, no more. Here is a link to my previous question and then below is my present question;

I am running a fully updated Windows 11 computer. I have 4 fully up to date browsers; Vivaldi 7.5.3735.66 (Stable channel) (64-bit); EDGE Version 139.0.3405.125 (Official build) (64-bit); DuckDuckGo version 0.126.3; and Firefox 142.01. I play Bejeweled Blitz on FaceBook. The game works perfectly on all browsers EXCEPT Firefox. When I try to play on Firefox I get a message that says I must "upgrade to the latest version of Flash:. There is NO flash anymore. Why am I getting this message on Firefox but the game works just fine on all other browsers?

for some weeks now, Firefox (latest, in Windows) crashes, or says 'not closed properly' and shows (usually) 12 'instances' in Task Manager when only one tab has been opened. I'm not techie, and need clear advice. Can anyone help please? Hugh, UK

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

The website you are blocking is on my domain and is my website. Why are you blocking it? Stop blocking it!

After recent update, I can not browse any addons. The site https://addons.mozilla.org does not open, shows the connection timed out. I uninstalled and reinstalled firefox deleteting all firefox related files. The problem still persists. Other than this all the using browsing I do are all working fine. Just this extensions I cannot browse. When I click the extension icon by default it shows some extensions, I can Install them. The problem is I can not browse them. Even the recomendation tab is also empty.

PS: I am using firefox on manjaro linux.

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

• (Nope - computer not eligible to upgrade to Win 11. My processor isn't fast enough, I think.)

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.

For over a week, Firefox always displays the message "Our servers are experiencing problems with our services" when I try to view a TV program on YouTube TV. Opera, Edge and my iPhone do not have this problem. I notice that Firefox doesn't store my location in the same place other browsers do. Could that be the problem?

I hate it when I have to use a different browser.
