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.

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

Firefox gives me a "Gah. Your tab just crashed." whenever I try to load a page. All pages do this. Steps that I tried to take to resolve this:

Started in Firefox in Safe Mode

Uninstalled all extensions

Refreshed, then reinstalled latest version of Firefox with new profile

In About:Config set browser.tabs.remote.auto to false and restarted. There is no remote.auto2; So I created one and set it to false then restarted.

I checked About:Crashes, but there are no crash reports.

I tried turning off hardware acceleration but clicking the open menu button does nothing.

I updated graphic card drivers to the latest version.

I rebooted my computer.

Other notes:

I had not installed any new software or updates prior to this happening.

All other browsers (Chrome and Microsoft Edge) work fine.

Any suggestions would be greatly appreciated. Thanks.

Ever since the end of February Firefox has had a habit of crashing on me at random, usually just a tab or so but there's been times where the whole browser just ups and crashes. I am using Firefox 73.0.1 (64-bit) on a Windows 7 Professional computer.

1. This mainly occurs when viewing a video (mostly Youtube), scrolling down on pages, or opening or switching to a new tab.

2. Beforehand if there were issues it would take a few seconds to load the tab, now it just instantly crashes.

3. I've tried uninstalling and re-installing, clearing everything, turning off add-ons, and changing options and nothing has worked. At best, I've stopped it from crashing on launch and disabling add-ons.

4. This issue does not happen on other browsers, nor has my computer shown any unusual behavior.

5. It did not start immediately with the new update, which I got the 20th. It started occurring a week or so after.

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

  • Running in safe mode
  • Using a different profile
  • Downgrading to an older firefox
  • Changing allowed CPU cores from 8, to 4
  • Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

Hi Everyone,

Trying my luck here as a last resort. I cannot read videos on FF (I end up with the following message "This video file cannot be played.(Error Code: 102630)") except Youtube ones.

I read few articles and already tried the following: make sure I have the latest version of FF, uncheck "Use hardware acceleration when available", install FFMPEG, install K-Lite (and restart FF each time).

Nothing worked so far so any other tips from the community would be great.

I'm using Windows 10 and have a couple of add-ons only (LastPass and uBlock origin).

Thanks a lot in advance,

Max

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?
