Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

As the title indicates, copy/pasting does not work.

I'm on Windows 10, have installed Firefox about two days ago (I've recently switched to it) so the version of FF is up to date. I've looked up a few fixes before posting and they didn't work:

- Tried booting FF on safe mode and it didn't fix the issue - it clearly isn't caused by an add-on (and I've never had this issue in my previous browser with nearly the same add-ons installed). - other people seem to have had the exact same issue multiple times and it's lasted for years, so it's clearly a problem on FF's end.

Here is the issue described more specifically: Copying things from a tab from FF and into the online version of Word does not work - when I try to, the intended selection: - disappears a few seconds after I've pasted - or it does not appear at all - or when it does, it erases the entire sentence it was pasted next to it, which you can imagine is absolutely bothersome.

I've also tried to copy/paste statistics from a site called archiveofourown.org onto another FF tab. - What ended up being copied is only the last character of the entire content I was trying to paste, which I think suggests there's some issue with what's contained in the clipboard.

I'm mentioning these two websites because I'm guessing that something about them is probably conflicting with the copy/paste feature, however I'm hoping no one will have the gall to tell me it's those websites' faults and that I should just stop using them.

When pasting (while having hopefully copied the former selected content- and no, it wasn't the case), it always pastes the content which was last copied into the clipboard prior to that very attempt, which shows that the clipboard's content was not refreshed with the last selected copied one.

I'm surprised to see that FF has had such a glaring issue for years and for many other users, and updates have never given a fix for it. I'd like this issue to be fixed properly, because I'd hate to have to switch back to my previous browser. FF sports so many nice features that other browsers don't have, and it'd be a shame to ruin the experience with a bug so basic as the copy/paste feature being broken.

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

  • This happens for any filetype, from any source.
  • It started happening about a month ago.
  • Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
  • If it's a small file and I try repeatedly, it sometimes will eventually download.
  • Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
  • I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

  • Used Refresh Firefox
  • Cleared download history
  • Changed download location
  • Reset browser.download values
  • Disabled firewalls and antivirus/spyware
  • Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
  • Cleared cookies and cache
  • Ran in safe mode
  • Verified Temp folder filepath was valid
  • Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
  • Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

  • I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
  • Verified places.sqlite was not set to read-only
  • Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

It says so in setting (topleft) and in about firefox (instead of update button). I have been able to change all other settings that I know of.

Hello, everyone. My Firefox (v76.0.1, Windows 10 Pro 1909) can't access the English Wikipedia (en.wikipedia.org) and some other sites I need to work with. This started happening suddenly Tuesday night.

This is the error (in English, since my Firefox is in Brazilian Portuguese):

Secure Connection Failed

An error occurred during a connection to en.wikipedia.org. PR_END_OF_FILE_ERROR

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

upload.wikimedia.org gives me the same error. The bizarre thing is that Wikipedias in other languages seem to work normally. Other browsers work fine.

Searching it online, it doesn't seem to be a common problem, and it just started happening by itself. I don't remember installing anything on this PC that day. My only antivirus is Windows Defender. I don't use any VPNs.

Tried all solutions I could find on Google. So far I did:

  • Ctrl + F5
  • Edited the hosts file
  • Deleted cert8.db
  • Changed network proxy settings to No proxy and Automatically detect proxy configuration (was in Use system settings)
  • Toggled DNS over HTTPS
  • Went in about:config and toggled network.dns.disableIPv6
  • Started Firefox in Safe Mode
  • Backed up the profile folder and just let Firefox create a new one
  • Rebooted my router

None of that worked.

I work with site builder platforms and since yesterday the error is starting to creep up in those servers, too.

Any ideas? I just noticed that Wikipedia search is gone from the list of opensearch engines also… This is getting increasingly bizarre…
