Firefox Community Forum

A client of ours has recently raised an issue with with us stating where right-click, Paste does not work when adding text to a new LinkedIn post

After investigating, we have been able to reproduce the same behavior on our devices.

However, from our testing, we can right click to past on comments, messages and searches just fine

Troubleshooting already attempted:

Cleared Firefox cache Performed Firefox refresh Tested across multiple devices

We have confirmed this occurs on:

Clients device My work desktop My work laptop My personal desktop My Personal Macbook

This issue appears to have started after updating to Firefox version 151.0.0. I know this as i have tested this on my work laptop, appeared to work fine then stopped working after manually updating from 150.0.3 to 151.0.0.

Please let us know if there are any known issues, additional troubleshooting steps, or if further diagnostic information would help I have attached screenshots of the issue.

I have also tested this in the Google Chrome web browser and appears to be working correctly as also seen in the screenshots.

Hello all

 Firstly I have been using Firefox for about 2 decades and it has always worked perfectly - you can take a bow.
Now for my problem
I have been using Firefox for internet banking for many years without any problems - the usual login, password ans secret questions. Just after Xmas my bank updated it's website and suddenly nothing works. I was told that it now only works on Chrome and NOTHING else - not Firefox, Edge or anything else. I am able to log-in but can't see my account balances or perform any other functions - it just jams up to the point that I even have trouble closing Firefox.
I use Firefox exclusively because I don't trust Chrome or Google - they are just a massive data collection/sharing operation. I have Chrome Mask installed but it just doesn't make any difference.

 Is there anything that I can do or add-on to over-ride this problem?

I am running Mint Linux 22.2 with Firefox 151.0.1

How can I prevent firefox from DELETING all my bookmarks EVER AGAIN! FUCK!!!!! They did some kind of screwy update and reverted my bookmarks back by 6 months and I can't get them back. And yes, I saw all the backups they "stored" but they are not in there.

Hello! Is it possible to recover older open tabs from a broken device that had sync activated? For a while they appeared in the hamburger menu in the top right, but now they suddenly disappeared, and under the "connected devices" I cannot click the device or anything. It went broken 2-3 months ago. Best wishes!

I can't get my Firefox icon to go to my desktop and become active. I also cannot uninstall Mozilla - it just allows me to attempt to repair it. My icon also shows Firefox 2 for some reason.

My main Extension is 1Password which I rely on. I do have a few other extension and the same applies to them. The Extensions work fine and I can have multiple Firefox windows open with no problem, however if I click on a link in an email (often necessary) it opens a Firefox window as expected but my Extensions are not available on the toolbar and do not work. I can add them to the Toolbar but 1Password does not work in this window (opened from the link), whereas it works in any other Firefox window..

I realized today that my tab groups were all gone and I believe it is because I erased all of my search history about a week ago. Unfortunately I did not realize that clearing my search history would irrecoverably delete my tab groups, and I think it would not be intuitive for many other people either.

Ideally I would like to see a specific option to keep or erase tab groups when clearing search history but in the absence of that I think at least having a warning that you will lose your tab groups if you follow through would be very nice.

Anyone else having issues with facebook reels/videos not loading?

In my feed, most of them just show a black frame and if I click on them, the screen goes black also.

I was playing a game hat required dialogues and I accidentally clicked the "Stop site from making Dialogues" check box and i cant undo it, I've tried reloading the site but that didnt work, and that was the only suggestion i could find.

Please can you (a) add to menus, or create a button, so users can see the tab groups they have created and (b) prevent upgrades to Firefox from deleting a user's tab groups.

after last update stop working .if I use ctrl v it will paste in. When i try using the mouse it doesn't have paste in the block that pops up.

I can click and paste in the condition box but not the description box.

If I use edge it works. I don't want to use edge

I have also cleared cookies and cache

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

I am not being allowed to access some websites because of my 'Do Not Track' status still being broadcast. I had the field set to 'Yes' when the field was removed. I am not allowed onto these other sites because of my 'Do Not Track' status. How can I fix this ? I was planning on using Firefox when I go to Apple silicon later this year - but not if I keep running into problems before I switch.

Right now when I right-click to translate a word or a full page, it automatically picks one of my country’s regional languages as the default. I only want translations to go to English, but I can’t find any setting in Firefox to change that. How do I make English the default (and only) translation language?
