Firefox Support Forum

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

Recently firefox stopped playing audio, I have searched through the settings multiple times, tried safari and google chrome and they both still work so here I am for help.

Running 127.0.1 (64-bit) on EndeavourOS, KDE Plasma, using Wayland. I've had severe crash issues and when troubleshooting I noticed this

Error: Failed to open Wayland display, fallback to X11. WAYLAND_DISPLAY='wayland-0' DISPLAY=':1'

pops up every time I start Firefox via terminal. Why wouldn't Firefox be able to open a Wayland display? Trying to force it with MOZ_ENABLE_WAYLAND=1 firefox doesn't do anything. I get the same error message.

I just noticed today that none of my various folders storing important bookmarks work anymore and they have all lost their own indiviual logos. Instead there are just globe logos!? This is very recent so i can only imagine so kind of update has done this?

Can i get these fixed?

I recently suffered from the "127.0.1" not compatible error. Eventually I was persuaded to reinstall firefox from the Mozilla oficial site using Edge, despite having reservations about losing my passwords etc. which has happened before. Fortunately, the installation routine included an update option which preserved all of that. However, my menus bar (File ...... History, Bookmarks...) is missing and I cannot find any way to get it back. I rely upon it to restore previous sessions, because I routinely have the same 7 tabs open and want to be able to get them back after an update or laptop shutdown, and also use it to search history and find bookmarks that are not in the bookmarks bar. Any help welcome.

As an asside, my pet hate is updates to any application that remove, move, or hide a very useful feature without explanation or warning and claim to be to "improve the user experience". Take it from a long standing user, they don't. Quite the contrary.

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

So i'm a basic PC user and not a Pro to solve Problems related to Web browsers. İ wonder if this happens to any one out there using Latest version of Firefox. (127.0.2 64bit) PS:İ use a app called user agent switcher to fix freezing or lagging or buffering. İ have read some where on the internet that youtube is doing it on purpose?. This happens only with Firefox but not with Microsoft edge.

For two days will tab crash for TikTok. For years, will not allow access to certain sites and no contest entries for the last few months. Worked before. No phone help and to download the browser doesn't work. I was upset as won't load TIktok and I NEED IT as use it daily. Please fix it ASAP!! I wasted time contacting Monzilla, as was only link for Firefox. They told me no help wasted today.

Hi I am currently unable to retrieve bookmarks and website passwords stored in your browser so please help me to retrieve them.

I request you to restore the password and bookmark from my browser last week

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

• I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
• I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
• This does NOT happen when playing in a private browser window, either Firefox or Chrome.
• Having the Mozilla VPN on or off has no effect.
• I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
• This does not happen with Vimeo.
• It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.

In my experience with the TF2 Wiki page, clicking an audio file link would open a new tab where I can play the file. Since I've moved to firefox, I can no longer do this. Instead, the file downloads. Is there a way to change this? I saw in another post that you have to change the flag media.play-stand-alone to true but it was already true.

Download Web plugin to access my Security DVR. When I type in the IP of the DVR, firefox will momentarily go to the plugin but then says it needs to be downloaded. HELP

Thank you

You haven't installed the plugin or it is not the latest version.

Please click download to download the latest plugin.

Please close browser before plugin installation.

Hi, Archived thread on this from 2023 has no answers. Why is this browser so slow now and why is it glitching with resizing my windows? Beyond a total reinstall - how completely inconvenient - I would like an EASY FIX.

NOTE TO MOZILLA - WHY DON'T YOU HAVE A SOLUTION FOR THIS, NO REASON TO GO TO COMMUNITY 'IN CASE' SOMEONE HAS THE SAME PROBLEM!!!

Recently Roboform add-on has not been working with Firefox I have made several efforts to ensure that it works automatically filling in passwords as previously but the add-on does not seem stable, afte reloading it works briefly then stops again. Has anyone had this problem and found a resolution? Thanks
