Firefox 技術支援討論區

Hello all, I regularly open up pop up windows to do my job, containing lots of column data. Until recently, the columns would squeeze down as small as they could - depending on data field and font size - meaning the bottom scroll bar was unnecessary. However, in last 1-2 weeks(?) the data columns seem happy to spread themselves out menaing I always have to scroll right to see the last few columns. Is there anything like a 'make the columns fit if they're capable of doing' command/shortcut? Thanks all.

Is it still necessary to use both !important and @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul) inside userChrome?

Since last weekend or thereabouts (17 July 2021) my Firefox on the 3 devices/platforms I use (see title) is not connecting to a specific website. Edge connects and is usable.

There is no error message, the screen in the tab remains blank and the activity indicator stops after a few seconds.

The website address is https://colony.litopia.com . The website is functioning and I have just used it, loaded images etc using Edge - I am a writer and use it every day, usually LOL.

All the other sites I use are ok, as is the main domain https://litopia.com . The hyperlink from the parent to the subdomain also hangs in the same way. I have spokent to other users of the site and they say it is ok, although it is noted as usually being a very slow site.

I have tried connection via cellphone router and wired broadband from different physical locations. Firefox troubleshooting not reporting any errors.

I use adblock on Win10 and Linux and have tried disabling that. FB container only on win 10. All platforms are up to date with Firefox. 90.0.2. I believe the issue arose when I went to 90.0

I haven't shared my data because the devices are disparate.

Comments appreciated, thanks.

Managing profiles: My Firefox since rel 89.0 crashes several times A DAY. The last time it crashed 6 times in a row then WIPED out my copy and gave me a new copy, BLANK of everything. I am no rookie to Firefox as my first version was 1.0 when I converted from Netscape Navigator long ago. The rub is PROFILES. I have too many to manage now and need to get rid of some but Moz:lla in their infinite wisdom does not put a date, what was the LAST one.... and one has to search to find the LAST profile that has your latest modification, data, etc. I am fearsome in deleting any as they do not seem to be in any order and I get a SERVE warning when trying to delete. Since the new releases crashes all the time, to do critical work I have to resort to UGH, "EDGE' until Moz://a gets a solid release and hopefully STOP TRYING TO COPY EDGE AND CHROME.

Any advise will be appreciated. [except advise to use EDGE or CHROME].

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.

One site that I use often is only showing JSON 404 error code. The site works fine on another browser, on a cell or tablet. Doesn't work on my computer on Firefox browser. I tried refreshing the page and the browser - problem is still there.

When I launch Firefox, it refuses to open My Yahoo, which is the home page I have been using for many years. My.yahoo.com is still entered in Settings as my home page. Even if I type the URL into a new tab, it will not load. I have now switched to Edge as my default browser and it is working just fine. I would like to go back to Firefox, but there is no way I can do that if it wont even let my use my preferred home page. This is the second time I have presented this problem. So far - no response. I can be reached at ... @yahoo.com.

My switch from the release version to ESR seemed to go well, but my history and many of my settings and data, including my pinned tabs and extensive notes used by add-ons, were gone. I managed to reconstruct most of them, but was distressed to find that when Fx updated my ESR version those settings were again gone.

I have again restored most of the lost settings (including the one not to automatically update!) but I know I can't defer Fx updates indefinitely, and I also expect I may want to return at some point to the release version--and I desperately don't want to have to reconstruct my settings any more (or at least more than one last time). I'm not concerned about the loss of my history

Since I'm prepared to note all my settings first, starting fresh seems like a viable solution. I just need to know how (unless you can suggest a better option). I'd be happy with either the release or ESR channel.

As the Title says if i click the Middle-Click on an link, it opens a freshly new tab instead of the link. I've tried changing things in the about:config but nothing helped. If anyone could please help me because its an habit. Btw i tested it in Chrome and in Chrome it works normally.

When I sign in to Outlook, I have to refresh the page, then it tells me that the password is wrong (which it isn't), so I have to sign in twice to get my email account.

not sure why it did since i've been receiving auto emails from firefox for signing in just a couple of minutes ago, but here's my request, please resend confirm email and unlock account, please and thank you

Last time Firefox updated, I managed to find information online about moving the website tabs so they were below the bookmarks instead of at the top of the screen. It was a huge pain-in-the-butt to do.

After a recent re-install, the tabs have moved themselves back to the top of the screen and nothing I do seems to be able to move them back below the bookmarks.

Is there a way I can move the tabs that doesn't involve spending hours hunting through posts on the web, changing hidden Firefox settings, and recoding .css files?

If not, why do you not give the option to move the tabs wherever the user wants? Especially when it makes far more sense to have the website tabs directly above the website being viewed, at least in my opinion?

I'm currently using Firefox 85.0.2 (64-bit).

HERE IS THE ANSWER Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it. You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right --menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/

Also to make the tabs wider or narrower, modify the line which is coded width: 50vw !important;

Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit. When all the toolkit options appear change the one which says toolkit.legacyUserProfileCustomizations.stylesheets to TRUE by click the icon in the right hand column. Than close Firefox and reopen, and check how it looks This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.

Hi,

I had been using this addon: [https://addons.mozilla.org/en-US/fire.../video-speed-control/] and I had no problems with it, until today when I went to increase the speed of a video I was watching, and it wouldn't work no matter what. Clicking to increase the video speed doesn't make the video go faster, as it should.

I uninstalled it and installed many other video speed controller addons, one by one, but none of them work at all either!

The video speed control had been working perfectly well up until now, and I hadn't modified any settings or anything else, that might cause it to stop working.

So how can I get this video speed control addon: [|https://addons.mozilla.org/en-US/firefox/addon/video-speed-control/] to work for me again? Help! I don't want to switch web browsers.

Thank you very much for your time and help, I really appreciate it!

I've been using site https://mail.aol.com/webmail-std/en-us/suite for years to log in to AOL email for years and now, with Firefox v90, it takes over 2 minutes to load. It takes only a couple seconds with the Edge browser. I've tried troubleshooting mode, a refresh and a complete re-installation without any improvement. This never happened in previous versions of Firefox.

Any help is appreciated, Gary S.
