Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

Started receiving pop ups stating virus attack from Mozilla and via cq5g6mojubcc7385jauo.deviceconnectnetwork from Mozilla showing McAffee, Critical Virus Alert, Virus attack. Receive 3 at time and I can't see the right side of my scree and I need to. Is this malware and if so how do I remove it fast? Thank you.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

I have been unable to connect to any website through firefox. Every other browser works. Can someone please help?

The error is:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.google.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I want to turn off the hover preview feature. First I went in settings, but that disabled only the thumbnail (browser.tabs.hoverPreview.showThumbnails in about:config is set to false and saved). Then I went in about:config and manually set browser.tabs.hoverPreview.enabled to false as well, that disables the unwanted feature completely.

But every time I restart the browser it's turned back to true (just hover.Preview.enabled, not hover.Preview.showThumbnails). Can I save my settings? It's annoying that I can't opt out.

Hello. Since re-installing ZoneAlarm Security Suite (due to a ZA problem) last evening, after I turned on my pc today I am getting a new tab opens up on every FireFox browser window seeking permissions for "Harmony Web Protection Privacy Policy". (There are four new tabs for that which have opened since I commenced typing this!).

Is this a ZA problem or a Firefox problem? Also, please, how do I get rid of these damned new tabs? TIA.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

For the past few days when I have tried to log into a few websites which use TLS/SSL I have gotten PR_CONNECT_RESET_ERROR. Please see the attached screenshot for more details. This issue was observed ever since I updated to Firefox version 124.x. Prior to that the websites were working fine.

When I try to access the same websites and try to log into them using Microsoft Edge, I do not face a similar issue. They work fine.

I have cleared the browser cache, restarted firefox, and then tried. Still faced the same issue. I have cleared the DNS cache of Firefox browser (about:networking#dns) and then tried. Still faced the same issue. I have opened Firefox in Safe mode (Menu > Help > Troubleshooting mode) and still faced the same issue.

Can someone please help me in fixing the issue? I would like to refrain from using MS Edge or chrome browser.

Just in the last few weeks, "buttons" on web sites do not work in Firefox, but work fine in Chrome. Example: https://www.mealtrain.com/users/sign_in/ The sign-in button does nothing in Firefox, yet works fine in Chrome. V. 125.0.3, Windows 10.

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.

I'm trying to use the built-in PDF Editor features after finding out about it but every PDF file I open with Firefox has the options grayed out (as shown in the screenshot). What should I do to re-enable the features?

I have the latest FF browser. I'm not using any proxy service, just spectrum connection. when i try to access my credit union account, i get this message

"Error: "WWF2TUh4dnM=" - You're using an outdated browser or are using a Proxy service which is unsupported. Please update your browser or turn off your Proxy to continue, thank you."

how can i get past this? All help appreciated!

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help
