Diễn đàn hỗ trợ Firefox

Hello how are you? I'm seriously considering switching to Firefox Browser to have more control over my privacy. However, the university makes use of Google Meet and the background is only enabled for Google Chrome and Chromium bases. So, I would like to know if there is how (modification in config, extension) to enable the functions. Thanks!

I can't find a way to enable natural scroll with the touchpad - down movement on the touchpad means the screen moves down - in Firefox. I've gone into about:config and set mousewheel.default.delta_multiplier_y to -100, but that only affects the mouse, not the trackpad.

I'm posting this as a question because other ones on the topic are closed for comments

Anyway, I seem to have found the solution - sync clipboards using ClipIt (http://clipit.rspwn.com/) or some other clipboard manager

My case - hopefully FF devs find this useful: 1. Paste works - I paste screenshots, text copied from terminal, and other stuff 2. Copy text from FF page, or hitting a copy button on a page, works only partially - I can paste in other GUI apps but not in terminal

   The snippet does appear in ClipIt. When I select it, it becomes available to paste in terminal

3. Copy text from FF address box works - I can paste anywhere

The recommended solution from FF support is to "reset", which means "factory reset" - this doesn't solve the problem and kills all yous addins, bookmartks, settings, etc. FF support stop suggesting stupid solutions!

I have also played with the settings - there was something there wrt copy/paste - it worked for a few hours

My guess is that Firefox is doing something wrong when placing things in the clipboard. Placing in the wrong clipboard or maybe you should place it in multiple clipboards and please make it configurable in case you screw it.

Hello,

https://addons.mozilla.org/en-US/firefox/addon/epubreader/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

Installed on 90.0.2 (64-bit).

Works fine when opening an EPUB from the browser but if I double click on an EPUB file it opens multiple tabs & will not stop, has anyone else encountered this & been able to fix it?

Windows 10 Asus laptop, no issues with anythng else, am wondering if Windows 10 App settings could have anything to do with it but have not been able to find a way to disable default settings completely? Alternately is there something I can do via about:config on Firefox to alter this?

Ideally I don't want to have to uninstall Firefox completely in the hopes of seeing if a fresh install will stop this issue arising.

Thanks

I'd like to have, in my one firefox account, a 'private' profile with my private life bookmarks and a 'work' profile with my work life bookmarks. However, this doesn't seem to work. I open firefox with work profile and see my work bookmarks, then I close and reopen with private profile and see my private bookmarks, then I close and reopen again with work profile and now I still see my private bookmarks instead of my work bookmarks. Firefox just unsolicitedly takes the private bookmarks over to the work profile. This can't be how it's supposed to be, right? Because what would be the point of having different profiles? I hope you can help me with this.

I need to automate the deployment of Firefox along with the extensions. I put three extensions (uBlock, Translate Web Pages, and Auto Tab Discard) in the /usr/share/mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/. All extensions load normally, except Auto Tab Discard. When running firefox with the -jsconsole option, I see what the screenshot shows (the message "Invalid addon ID"). But the installation to user profile is successful. I add the extension ID to manifest.json, and get the following output in the console: addons.xpi-utils WARN addMetadata: Add-on {c2c003ee-bd69-42a2-b0e9-6f34222cb046} is invalid: Error: File /usr/share/mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/{c2c003ee-bd69-42a2-b0e9-6f34222cb046} does not contain a valid manifest(resource://gre/modules/addons/XPIInstall.jsm:669:11) What can go wrong?

System: Debian 11 (bullseye) Firefox version: 91.4.1esr (amd64)

If you need any other information, please ask, I will write it down.

Hi, Since a couple of days ago the "Print Preview" feature is not working properly again. I think we had an browser update. We had another one today and I was hoping the problem was going to be fixed but it was not.

I have the Print set to old (false) mode. I have used this mode for years to print all of my documents and webpages.

This is what is happening. I do my print preview and adjust the scale number accordingly. The print preview shows, I adjust number of pages, preferences etc. then hit print.

The page that prints is not complete. Is missing the part of the right side and bottom. I have not changed any printer settings. I have also changed it back to the NEW(true) printer mode an the exact thing happens. It happens with both webpages and documents. I first realized what what going on when I printed my bank statement and it was missing the right side and bottom of each page.

THIS IS NOT PRINTER PROBLEM!!!!! Using the EGDE and Explorer browsers, the pages print perfectly so it has to be a Firefox problem.

Can you please help me solve this problem. I hate to have to use another browser just to print. I have enclosed pictures of what is happening.

I need help changing my keyboard layout in Firefox, as I´m not able to find the right settings. I'm currently using a British keyboard (with @ below the 'Esc') layout on a keyboard with American keyboard (with ` below the 'Esc') layout. I´m thankful that it is still a QWERTY-layout but for example the ´ and ' are on different places than I can see and from what I'm used to.

So, how can I change the keyboard layout on Firefox?

On my OS I sure have the right settings for my keyboard, I think it changed on my web browser when it updated.

Please ask first if you don't understand the question, thank you.

I operate a website in which the body background is black. My background image has a black background. And inside the body, I place a white-background div, which carries the text. My issue is, the scroll trough is some shade of black and the scrollbar is a lesser shade of black.

On any white-body website, I have visible shades of grey and I can see my scrollbar controls.

Where do I go to apply !important CSS rules to my browser interface? I want to establish a suitable color scheme for my scrollbars that override website CSS.

//EDIT: I've found a few typos and fixed them, above. I have then added the text below:.

If I edit the stylesheet to change the body background color on the website, it affects the scrollbar coloring, and ruins the website appearance.

Only if some developer would use the Linux system colors in Firefox so that theme colors are the same in Firefox as they are in the Linux apps that follow the rules, then Firefox would be a much better browser. Is there an add-on that will resolve this issue?

Is there a CSS fix that I can apply? In past decades, websites wanted to color the scrollbars but they are the property of the user, not an extension of the website. What's become of that idea?

Hello, recently Ctrl+Shift+M has been grabbed by Firefox but I had already mapped this shortcut to a command in my desktop, how do I disable this shortcut in Firefox? Thanks!

My screen shot tool disappeared this week, as did my "share" option (email, Twitter, FB, etc.).

What happened? How can I put them back on my toolbar?

Also, looking for a hopeful solution without having to add a third Firefox bar. It makes my screen (small laptop) too small.

TIA, Susan

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

Hi there. When watching twitch or youtube on one screen everything is just fine. I do have 2 monitors, and sometimes i watch 2 twitch streamers at the same time. or one with youtube and one with twitch. Everything have been working just fine, but for maybe 2 weeks ago, the UI or stuff around the video\stream im watching is flickering. This only happens when watching 2 videos at same time. It flickers on both. The video itself is just fine, but everything around is flickering, like chat on twitch, or the recommended videos on the rightside of youtube video window. Turning Safe mode on and it stops. uninstalling all addons, and the problem is still there. And still work fine in Safe mode. Havent done any changes anywhere with firefox, and only use 2 addons. And if im watching 2 videos and scrolls down and up on one of the screens, it flickers even more. Hardware Acc is off.

When I start firefox on my laptop, Avira gives me a black list warning and stops some processes. During my browsing with firefox, the warning comes back and back again. What can I do to stop it?

My Firefox browser is showing an incorrect location. If I check my location on any other browser it shows true but Firefox is way off. Causing sites to freeze my accounts for irregular location activity. Have already restarted modem, PC and browser but location in Firefox remains the same bad location while all others show true location.

Hello Community, Upon updating Firefox today, some sites are cutting off the majority of the page and printing in the top-left corner. I've tried the following and none have helped:

Close and reopen Firefox Refresh Firefox Uninstall and reinstall Firefox Restart my computer Print from the system dialog Print from the Firefox dialog Cleared all add-ons Print from a different computer with a different FF account Print to a different printer Print to PDF

I've attached the PDF (after converting to JPG as required by this page) which was printed through Firefox which shows the issue. The same page prints normally in Edge and Chrome. I printed the same page yesterday without issue and when I did the test from another computer with a different FF account, it printed normally, the browser updated and had the problem so it's definitely something with the most recent FF update.

This may seem minor in scope since it only effects certain sites but it's a huge problem for me as I print quite a few pages from this site daily for order processing. Thank you to anyone who can help!

Trying to use the seach box in the centre of the Firefox homepage (google search engine) .. everything I type goes up to the address bar . Tried changing settings - I see there's a search box option in the 'tool bar' which looks to be up at the side of the address bar. cant understand why we need another one as well as the one in the centre.

Also by turning off suggestions and not choosing the 'search box option in the 'tool bar' , the address bar is now only accepting URLs so searching isnt working.

So ..1. Is the search box in the centre no use?

        2.  Does search work with all suggestions turned off?

I just upgraded from FF 89 to FF 90 (on Ubuntu) and the drop down menus (accessed on right-click) are now transparent. I have changed the theme, changed my desktop theme, started FF in troubleshoot mode, disabled acceceration in about:config, and it makes no difference, the menus are still transparent. This makes it difficult to use the browser.

Is this fixable or is it a bug in the latest release?
