Hello After last firefox update this page mail.proton.me (specifically: https://mail.proton.me/u/0/inbox) does not load for me.

It works in chrome and edge but not firefox. I cleared my cookies and cache but it did not help. All I get is blank white page and sometimes error message. I attach screen from my F12 menu when I try to load page. In brave for example there is much more activity than in FF.

Secure Connection Failed

The connection to the server was reset while the page was loading.

I'm no longer able to play Youtube videos on Firefox. I've tried everything from re-starting laptop (this worked initially) to refreshing/updating Firefox browser as well as clearing Firefox cache and cookies. Any help will be appreciated.

Thanks, MC [email removed]@aol.com

p.s. Youtube does work and play on my Edge browser

I want to cancel what I was doing tonight and do it another day when it is not so late. I have more office work to do and it is after midnight so I do not want to mess up my windows 7 as I hardly know what I am doing. I need to contact you when I have more time. I am too tired and still have reports to do. Can I cancel what I was doing and try it again another day? I am wanting to get some medical records because I had to go to the ER a few months ago and need them for the Veteran's Assoc. to file a claim

When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?

Since the last update (136.0.4 (64bit)) firefox only partially shows an embedded google spreadsheet. It was fine in the previous version. Tried turning off enhanced tracking protection, but that didn't do anything.

After firefox update, start page changed to first photo i added here, second photo is how it was before, is there any way to get it back? Before update i had version 131.0b9, now its 136.0b1

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

Hi there, I'm trying to upload a new version of my browser extension (version 1.4.5), but the submission is being blocked due to a version number conflict. The issue is that I accidentally submitted a different extension under this listing with version 1.7.7. I reverted it immediately, but now I'm unable to upload the correct version (1.4.5) because it's considered a downgrade.

I really don't want to change my extension’s versioning just to get around this, since 1.4.5 is the actual next version in my release cycle. At the same time, I don’t want to stop updating the extension on the Mozilla Add-ons store. Is there a way to resolve this?

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

I have tried MANY times to make Firefox remain persistent as my browser. It appears I should log into an Administrative account to do so. Microsoft Edge appears to be the problem by remaining the default. I was told by the Tech Sprt for my Asus laptop to "delete" Edge. I entered the Administrative account using DOS. So many changes have taken place since I last used this account that I'm uncomfortable trying to take this approach. I was led to an administrative directory using "search" end while there was able to get a directory listing using DOS. But can't proceed. I really need the Windows pictorial version to proceed or technical support (preferred). Whoever helps must be fully capable.

Asus TS said I must delete MS Edge. The person seemed capable, but if I delete Edge, which I haven't found a way to do so safely, that may create problems but makes sense to do so because of the interference of MS Edge. My memory on how to proceed is that this process was MUCH less complex. I've read a number accounts by others with the same problem. My reasons for using Firefox, as an private engineer are to help prevent the stealing of intellectual property from wherever. Otherwise I'll have to abandon everything.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Hello, I have Firefox set to open the tabs that I had open during my last session. (General > Startup > Open previous windows and tabs). When I open Firefox, it does give me all the tabs that were open in my last session. But it does not give me the current pages. It gives me the pages as they existed when I closed it.

Is there some way to have Firefox refresh the tabs when I open the browser? I seem to remember this happening in the past. But it's possible I was using a different browser then.

Now I'm using version 133.0.3, Firefox for Linux Mint mint-001 - 1.0. Yes, I realize this is not the current version. If it's possible to get this feature with the current version, I'll be happy to upgrade.

Thank you very much.

I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.
