Firefox 技術支援討論區

I attempted to reuse the Chrome fix that was successful for previous versions, but that did not work. I want my Tabs on the Bottom where "I" put them, not they way Firefox thinks I am supposed to have them I am sure others are having the same difficulty.

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

Since the new update, tabs are on top again. And the fix for the last time it no longer worked (as usual) is not valid anymore. What must I do now? And why is firefox so set on placing the tabs on top? Thanks

Having some trouble with Firefox and I'm at my wits end on how to fix it. Clicking the Firefox icon in Windows 10 (whether that's in the Start menu, the taskbar or the app itself in Program Files) won't launch Firefox. The blue loading spinner appears briefly next to the pointer, then disappears. Sometimes a Firefox process appears in Task Manager then instantly disappears, but sometimes it doesn't. Here's what I've tried so far:

- Restarting - Reinstalling - Deleting my Firefox profile and all Firefox app files - Launching in safe mode by holding shift - Launching in safe mode by adding the "-safe-mode" comment - Running as administrator - Checking it's not being blocked by antivirus - Loading the Firefox profile manager by typing "firefox.exe -P" in the run dialog box. This does the same as trying to load Firefox - nothing happens

I can't think what else to do. It may be a coincidence, but my primary monitor died, I restarted the PC and then Firefox wouldn't work. I can't see how it could be related, but who knows.

Anyway, any help would be greatly appreciated!

I have done this before successfully but now, and the last few times, all I get is an empty folder when trying to import bookmarks from Chrome to Firefox. As I want to cut the tether to Chrome but want to save bookmarks this is important to me. I'm following importation instructions to the letter.

So, on my Firefox setup I use two extensions to circumvent website blocking in my country - one is an extension to make a specific website always available. The other is AnonymoX which I use for general purposes.

A few days ago I upgraded to Firefox 71.0 as well as updated my Windows 10 to the latest 1903 version. Today I noticed that both extensions have stopped working. AnonymoX just doesn't work, whereas the other plugin, upon activation, says (translated) "Conflict detected! Proxy settings are controlled by a different plugin or cannot be set up" Trying to circumvent a block (and only then - unblocked websites work fine) now either redirects me to the ISPs blocking page, or alternatively produces a "Secure Connection Failed PR_END_OF_FILE_ERROR" message after a long TLS handshake. Running the same extensions in Chrome does not reproduce the issue - blocked websites become accessible as usual. The issue also persists for three different connections - a public wi-fi network, a private network and a tethered 4G connection, all served by different ISPs. Finally, I am not running any anti-virus software or firewall. Thus this seems to be a Firefox issue and not a system or network issue.

This also doesn't seem to be an issue with the country's blocking system itself because other users around me are still able to circumvent blocks using the same extensions and I am able to circumvent blocks using a similar extension on my Android phone with a local SIM.

Things I've tried so far: 1) Made sure that both Windows and Firefox are set to not use a proxy

2) Reinstalled the extensions

3) Created a different profile in Firefox. The extensions don't work in the new profile either, although the PR_END_OF_FILE_ERROR does not appear - I just always get redirected to the respective ISPs block page

4) Cleared all cache, cookies, site settings etc.

5) Deleted the cert9.db file and let Firefox recereate it

So far nothing has worked. I'm frankly at a loss here. I have half a mind to just reinstall Firefox altogether since this is not my main PC and losing bookmarks wouldn't inconvenience me on it, but figured I'd ask here before.

i have had this issue for a year now, with no end in sight. my interface language on my entire computer is english. everything english. the keyboard is a german keyboard because i bought my machine where i live, in austria. but my written language and all dictionaries are english. same with my preferences in firefox, english everywhere. but for some reason the language constantly switches back and forth between german and english. look at the video, it's insane. i've uninstalled and started over. i've wiped the entire computer and installed EVERYTHING fresh. no change. when i install and use firefox, it comes back. it only happens in firefox. argh. screen capture of the language switching: https://youtu.be/gq8hXs5pXm0

For reasons unbeknownst to me*, Firefox started without restoring the tabs from my previous session. Exploring the forum for help, I found that menu "Help" > "Troubleshooting Information" will lead to a page on which one can find the profile folder, which in turn contains a folder called "sessionstore-backup," in which Firefox keeps a history of previous sessions' tabs.

While none of the files in that folder are intelligible, I can see from text snippets that a file called "upgrade.jsonlz4-20191202093317" is the only one that potentially holds a backup of my tabs. This file is just twelve days old. However, I cannot find a way to restore the tabs from that file as Firefox just keeps ignoring any changes that I make to the files name and folder contents. How can I restore my tabs from that file?

• ) There was no obvious crash, though Firefox just did not automatically load upon restarting my Macbook, which is always running the latest version of any software installed. This is nothing unusual in my experience, as it keeps happening about once a month.

Since yesterday, Firefox will not play sound on youtube videos and some other embedded videos (eg Newsflare). IE and Chrome will play the sound. Have checked the sound system and everything seems OK as music still plays and websites with sound still work. Someone suggested it could be a flash player problem, but have checked Adobe flash and it is the latest version. I really don't know what the problem is. As an aside, my Train Simulator (which is run through Steam) also has no sound and it did 2 days ago!, but my Flight Simulator (also on Steam) has sound! Just can't get my head round it!! Help!!

I exported my bookmarks from my Win7 laptop (via FF Quantum). Exported it onto my Win7 Desktop, with HTML extension. Then pasted it to Flash drive.

Note that when pasted, the file displayed as a Blue I.E. Explorer icon.

I then switched to my Win10 laptop, and pasted aforesaid HTML file into My-PC Documents. I then clicked Bookmarks / Show-All-Bookmarks / Import-Backup / import-bookmarks-from-html / this-pc / documents

then i clicked on the bookmarks.html file ...it displayed in the textbox. ......but then it stated "no items" in the grey area below where it states "Names Tags Location"

Please see my attached pic.

Updating to Firefox 71.0 was a catastrophe. I lost all my open tags though RESTORE PREVIOUS SESSION was enabled. I had quite a while, till I figured out how Firefox really does restore previous sessions. The lost tabs though were gone.

But one problem is remaining. I can not restore closed tabs with 71.0. Ctrl+shift+T does not work anymore.

How can I enable it again Or is there a new combination for it

After updating from Firefox 69 to Firefox ver 70.0.1 ad blocking add ons for Firefox stoped working. I tested the same issue in Firefox Developer Edition 71.0b5 and thete it works fine.

Can anyone tell me what me be the reason and how to fix it?

Spell check doesn't work I have been through the forum and tried the other solutions but noting works. Have ticked box in options under 'language', have added dictionary to Firefox, no dictionary option appears when I right click in text box. Spell check doesn't work on email, Facebook or anything!

Hi all, Is there a way in about:config to change the tab font to be bold? Or to change it to a font that is automatically bold (like Aharoni, for ex.)? Thanks! PS, if this requires a css file, I will have a LOT more questions, as I have never written one of those and being somewhat elderly, have never taken a computer course.

The help instructions for importing html bookmarks files do not match your pull down menu. There is no way to complete the import process. The screen shot below shows the window I get when clicking on "Bookmarks".

Using Options>Colors>I changed the background to "Black" and left the font "White", which was the default. I wanted ONLY the BLANK homepage black. I have a dark theme made by MaDonna. Immediately something altered, FF blinked (so to speak) and next ALL pages are a black background, including ALL webpages. Using FF instructions, I got back to a white blank homepage, but all the webpages have remained black. I've tried every combination (shown on your instruction page) to get back to a "white" background on the webpages. The "Always," "Never," only on ?? themes, clearing cache, returning to defaults, & I can still change the BLANK HOMEPAGE to either black or white, but nothing changes the webpages back to their normal views - white backgrounds. The only thing I haven't done is remove all cookies, because I truly do not want to do that.
