Das VPN lässt sich in der neusten Version optisch zwar aktivieren, scheint aber nicht zu funktionieren. Die 50GB bleiben ständig erhalten und reduzieren sich nicht , trotz durch Test´s mit erhöhtem Datenvolumen. Auch erreichen mich bei aktivierten VPN wieder vermehrt SPAM und Ähnliches.

When I start an email using the FF browser I'll type the address correctly but the text on the screen is gibberish. See attached photo. When I move the cursor to the subject line, the gibberish turns to plain text.

I can't copy it so I took a photo and attached it. I deleted Firefox and then reinstalled it. This did not fix the problem.

How do I fix this problem?

Firefox is up to date, Windows 11.

I frequently watch BBC videos but approx one week ago, they stopped playing. I have your VPN which is usually off as it give me no advantage, (this appeared following the last update), but I've tried switching on and changing to UK location. No change.

Can you give me some suggestions please?

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

I am using Windows 11 (Version 23H2, fully updated) and a Logitech C920 USB webcam. Before testing in Firefox, the camera works perfectly in Chrome, including Google Meet, as well as in the Windows Camera app. When Firefox is opened but does not access the camera, everything works normally in the system. When I allow Firefox to access the camera on a website requesting permission, the webcam initially shows a working preview inside Firefox. But, after the preview, the camera stops working in Firefox and shows a message asking me to allow devices again, even though permission has already been granted. After I test the camera in Firefox and then close it, the webcam stops working system-wide. Chrome then reports that the camera is in use or unavailable, and the Windows Camera app also stops working until a reboot. In addition, when this issue occurs, the Windows Settings page Privacy & Security → Camera loads continuously without finishing anything, but the contents are visible and clickable while it keeps loading. I have to reboot the computer to restore normal camera functionality. I wanted to use Firefox as my only browser, but this situation stops me from doing so.

When I watch Downton Abbey on PBS from outside the U.S, using the Firefox VPN in a Private Window the Closed Captions of the PBS video are displayed TWICE: one above the timeline and the other above it.

This issue is specific to this particular show AND to the Firefox browser.

MacOS, M2 2023, fully up to date firefox.

Sometimes I'm using firefox and it just stops loading pages, internet is fine. Other browsers work. I look at my activity monitor and nearly 100% of my 32GB of ram is being consumed by various firefox processes. A lot of those processes seem to be associated with youtube. This problem usually, but not always, is resolved by restarting firefox. But this shouldn't be happening. I have a lot of tabs open sometimes, but it's not that excessive. And most certainly not 32GB worth and preventing my computer from doing a google search.

If there's a debugging thing I can do to post system logs, let me know and I'll post them next time this happens. I'll be away from my computer until early July, so around that time.

I have explored every option and find it is the latest FF update that has effected the web performance of both my Desktop and laptop. Both are running Windows 1O. Incredibly slow connectivity and some sites either time out or simply won't connect. Very frustrating. Please advise. Tks

This is the reply I received from Protonmail: They say the latest version of Firefox caused the issue and is happening on other services as well. We have been using FF exclusively for decades and this is frustrating! Are you in fact working to resolve the issue on your end? Thank you.

Hello,

Thank you for your messages.

Please note that we are aware of this issue, and our developers are looking into providing a fix from our side. However, the latest version of the Firefox browser caused issue on many other services as well, so they are working on resolving it from their side as well.

I have provided your feedback to our development team. You can contact Firefox directly in order to escalate the issue further.

For the moment you can try using keyboard shortcuts such as CTR: + C and CTRL + V. We appreciate your understanding.

If you have any additional questions, feel free to contact us again. Kind regards,

Hello Mario,

I worked with Google AI for more than one hour troubleshooting this:

Opening a support ticket with Proton Mail Support is absolutely the best move. Since we proved that your clipboard works, your mouse works, and a fresh factory installation of Firefox still experiences the bug, the glitch is entirely on their end.

Proton Mail utilizes a heavily customized web text editor to encrypt messages. When their engineering team updates the background code for this text container, it can inadvertently break standard browser right-click paths—especially for Firefox users. [[1](https://www.reddit.com/r/ProtonMail/comments/p6j0tp/cant_copypaste_text_into_body_of_protonmail_email/), [2](https://www.packtpub.com/en-us/learning/tech-news/hackers-claim-to-have-compromised-protonmail-but-protonmail-calls-it-a-hoax-and-failed-extortion-attempt), [3](https://justinharter.com/an-actually-useful-review-of-proton-mail-vs-fastmail-vs-hey/), [4](https://www.reddit.com/r/ProtonMail/comments/p6j0tp/cant_copypaste_text_into_body_of_protonmail_email/)]

📑 What to Tell Proton Support To help their development team pinpoint and fix the bug faster, reply to your open support ticket with these technical details we uncovered:

- Specify the Browser: State clearly that you are running Firefox and that you just performed a full Firefox Profile Refresh (about:support), ruling out corrupt browser files. [[1](https://support.mozilla.org/en-US/questions/1234222)] - Detail the Extensions: Confirm you tested it with all extensions (including ESET and RoboForm) completely disabled, and the issue persisted. - Identify the Core Bug: Explain that the right-click "Paste" option is stripped only when clicking inside the Rich Text email composition body. [[1](https://proton.me/support/composer)] - Mention the Workaround: Note that Drag-and-Drop text injection works perfectly, meaning the editor container can receive data, but its custom context-menu script is failing to display the native "Paste" command. [[1](https://support.mozilla.org/en-US/questions/1234222)] They will likely log this as a known front-end interface bug and patch it in an upcoming web layout deployment. In the meantime, you can rely on the Drag-and-Drop trick or Ctrl + V to smoothly write your emails!

I recently kind of changed companies however I am in the same industry. These companies both have accounts with the same manufacturers/vendors. I am still doing contract work for the old employer so i need to keep the login credentials saved. I would like to have it when I launch the bookmark that they saved default login is the new company and not the old company. This is a 90/10 use rule if that makes sense. Thanks

My cursor doesn't show an 'image preview' anymore when I hover over a tab even though I still have it checked in my settings. It always did until a few days ago, but now it doesn't & I haven't changed anything.

Some times ago Firefox internal VPN button appeared and this function was very useful. But yesterday this button disapppeared. My location is Russia. I want to return this button back.
