Firefox supportforum

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

Have just noticed that there are no longer green Norton check marks against web results. Have spent all morning in live chat with Norton. They say it is the way it has been set up. Very disappointed as they check marks were very useful.

This problem occurs on My wife's and my machines. My wife has a printer. I do not. When we try to print the preview shows only a few lines or at best a half page. Even if we want to print multiple pages that's all that shows up. We have "print all" as the default setting. The problem started about a month ago. I think it has something to do with the newer versions of Firefox.

Hello,

I tried opening an .md file with Firefox. It seems that this was a bad idea. Now, my browser keeps opening new tabs indefinitely. I tried rebooting my computer (I am using Ubuntu), I tried removing the handlers.json files from the .modzilla folder in my home directory, but it has no effect: whenever I try to open Firefox this infinite loop goes on right were I left it closing the browser. Please help so I can use it again! Best.

I recently switched ISP and now when I try to google anything with firefox I keep getting this message appear:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot."

It prompts me to click 'I am not a robot' then pick out which lights have cars etc in them. Worked fine before the ISP change. Some notes:

- This does not occur on Microsoft Edge or Chrome. - The only add on I have is Ublock but it still does this when I have that disabled. Plus I have Ublock on Edge and there are no issues.

If it's my IP address, then why does this ONLY appear when I use Firefox? Surely it would also appear when using google on any browser if my IP address was in question...

From what I am reading online, my only option is to either: - Use a different search engine ; or - Use a different browser.

I'm curious to hear other people's thoughts on this.

I've tried EVERYTHING I can think of to fix this issue. When 'trying' to open a YouTube video in Firefox, I'm 'informed' that I'm offline - try reconnecting (or something like that). I'm NOT offline. Three other browsers have NO problem opening these YouTube videos; it's only Firefox. Can someone PLEASE come up with a REAL resolve to this issue? I don't want to give up on Firefox and go back to Chrome. But this issue is VERY annoying. Thanks to anyone who can provide constructive resolution(s). AL R.

Greetings, I experienced this problem with the prior update, now after the current update i get this" internal Server error" Hopefully you can straighten this out. I hate using Google for anything!

Regards, Chris

I removed the Firefox Relay, however whenever I want to open my email its still there and I have to keep entering my email address manually, How do \i get rid of it?

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?
