Firefox 技術支援討論區

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 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.

Followed community advice but the following fails to work.

1. open "Help -> Troubleshooting Information" & find button to access the profile folder

2. find this button under: Application Basics > Profile dir > Open directory=/home/ab2qik/.mozilla/firefox/p3bbumtq.default-release click this button to open profile folder in Explorer

3. create a dir=chrome in this folder(all lowercase) 4. In dir=chrome create a text file=userChrome.css(all case sensitive) 5. userChrome.css - paste in text below 6. paste below code into chrome/userChrome.css:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

1. personal-bookmarks .toolbarbutton-text { font-size: 15px !important; }

7. (Quit/Exit) browser & restart Firefox when you create or modify the userChrome.css file.

8. Firefox 69 & later

about:config > toolkit.legacyUserProfileCustomizations.stylesheets = true

set above pref to true this enables userChrome.css & userContent.css in chrome folder

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

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!

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 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?

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

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.

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.

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?

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.

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.

Problem with printing at reduced scale, did not notice it before a few days ago so could have been after a recent update. Am now using Firefox 90.0 for Linux Mint 19.3. Printing to US Letter size (which had been broken with "na_letter" being stuffed in to the config at one point, but I switched it back to "US Letter" and then it started working again a few months ago - Thank you).

I see some similar questions listed, so this may be simply adding information to something known:

Printing with "Fit to page fit" works fine, with correct preview. Print with scale set to 100% works fine, with correct preview.

Printing with scale set to less than 100% (say 70% or 80%) showed in the preview the page rescaled as expected. The actual printed output is also rescaled as expected, but the page size gets cropped at the right and bottom by what appears to be the same percentage, ending up with lost content. The bit that does print seems to match what is shown in the print preview perfectly, suggesting it would have been totally perfect if the print area had not been cropped along with reducing the text and image sizes.

I tried the "Print using the system dialogue" option, and the printed result had the same pathology.

Same problem also happens when I print to PDF. For this I tried doing the same thing twice, both scaled at 70%, and on comparing found that the preview in firefox had also become cropped a bit but not to the same extent. I did not notice any cropping for the first print to PDF, but now seem unable to get back to what I saw originally in the preview, with correct resizing and no cropping. Playing around some more with printing at 100% vs 70% vs 80% to "fit to page width", I seem to be getting changing crops happening each time in the preview for the reduced sizes.

But the preview and print are both still correct for 100% scaling and for "fit to page width".

Sample web page I used here was https://getpocket.com/explore/item/a-shoulder-workout-for-better-posture?utm_source=pocket-newtab The screen shot shows the preview after the first reduced print to PDF, with no settings changed. The little bit of side cropping seen in the preview did not happen when I did the first print to PDF.

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.
