Question The Firefox Bug That Will Never Be Fixed

[lokamoka820]

Does anyone have this bug in Firefox, or it is just me? How I can fix it?

It happens when I open a new page and try to copy some text from it immediately, the copy option is grayed out, it takes seconds to appear, and sometimes I need to refresh the page.

This is a known issue with Firefox. It's related to the browser's performance and how it handles rendering new pages. Unfortunately, there's no definitive fix yet. You can try clearing your cache, disabling extensions, or using the latest version of Firefox to see if it helps.

Never had this issue on Mac.

No problems here. Check about:config and make sure this is enabled.

dom.event.clipboardevents.enabled

This is what I found with a quick search:

When they going to fix the copy and paste in Firefox?

When they going to fix the copy and paste in Firefox? This has been on going for months now. When it does let me copy, then there are times when it will not let me paste. If I paste it to windows notebook and re-copy it it will then let me paste. I have cleared the cache, disabled add-ons...

Seems to be working on my end as well. I only have 2 extensions enabled, 1Password and F-Secure Browser Protection.

What extensions r u using?

That's my thought, too. If oldschool's link doesn't resolve it, to disable all the extensions and see if Copy comes back, if it does, then re-enable 1-2 at a time to see which one may be breaking that function?

Did you check out that link? Some of the commenters were experiencing the same as you.

 

[oldschool]

I checked it, and it is enabled,

Is it set to "True"?

It is working now without changing anything, as I said it happens occasionally, not always.

It is strange, but this is the most reliable answer that describe the problem, it was what I do when I face it and it is always working.

This didn't help in my case. It even broke text editor on some websites for me.

Issue will be fixed in Firefox 130.

First world problems I guess. Never faced that bug tho.

What I find annoying on Firefox is video and audio sometimes being out of sync. And when I rewind, it's normal again. I don't know what is causing it, why it happens or when it happens because it's all random. I'd report the issue to Bugzilla, but I think I'll wait for Firefox 130 to see if this will happen again.

Update: The bug has been fixed in Firefox version 130:

• Fixed an issue where Copy and Paste context menu items intermittently were not enabled when expected.
