Firefox Community Forum

I have been a Firefox user for many years and love it. Recently I am having lots of problems with entering information into fields (credit card number etc). I'm also having trouble logging into sites I have been using for years and other people are having the same problems. I have tried deleting cookies etc with no success. Any help would be greatly appreciated.

Hello,

When I attempt to open Firefox, I am getting a pop-up screen saying:

135.0.1 not compatible with min version >= 135.0 max version <=135.0

Also, I am being advised to reinstall Firefox. Do I need to uninstall Firefox first?

Windows10, Dell Laptop

Thank you,

Petrik

Unfortunately, I have lost all of my browsing history on Firefox. There are no recently closed tabs that I can restore, and I've also checked for recently closed windows, but there are none to recover. It feels as though my entire digital footprint has vanished, leaving me unable to revisit important pages or retrieve valuable information I was previously accessing. Please help me.

When I open a PDF in Firefox, a box covers the right half the page demonstrating the highlighter tool. It never leaves. It blocks half the page and prevents me from reading and/or printing. Please help. It's making my work impossible.

I am having a problem on Firefox AVC1 and AV1 1080p60 YouTube videos play really bad but VP9 videos play fine only 1080p60 is bad on AVC1 and AV1 720p60 and below are fine i fixed AV1 issue by turning off AV1 now they play as VP9 video 1080p60 is fine but when i force VP9 into AVC1 video that video only shows 360p this issue is only on Firefox i tried same video on Google Chrome it is fine there is there anyway to fix this performance issue

Here is my pc specs

CPU: Intel Core i3-2120 OS: Windows 10 Pro 64-bit GPU: NVIDIA GeForce 210 512MB DDR3 RAM: 6GB

There is no easy way to keyword search for websites on android (google, yt etc.), have to manually configure url for each site which I did on pc as bookmarks but they have no syncing capability and don't work when putting on android app. Also I have to put encoded url, otherwise it shows up as google results. These need to be fixed.

This is something I've noticed in the last couple of mouths...

Initially everything on Firefox runs fine for the first 1-3 hours, but after that the multiple YouTube website video tabs I generally have open, especially the very last YouTube website video tab that's open, or any new YouTube website video tab I open, starts to lag like crazy.

Using my mouse to click the play/pause on the video player, or pressing the play/pause function key or spacebar on my keyboard, takes a good 3 or 4 seconds before the input action is registered, and it's not just that but the entire UI of the web page itself is slowed down.

Doing simple things like clicking on-screen buttons to navigate, and scrolling down to load comments, or scrolling down to load other video thumbnails etc etc, takes a good few seconds to actually work.

In general the YouTube tab(s) become very slow and unresponsive, and it's not just the video player on the tabs - it's the YouTube website in general that is affected.

I don't see a substantial difference in CPU or RAM in Task Manager when these 'slow downs' occur, but the fan speeds inside my mini PC do spin louder and louder.

For whatever reason this problem ONLY happens with YouTube. Other websites via other tabs tend to run and function just fine 24/7.

I'm running the latest 133.0.3 version of Firefox, and my system specs are as follows:

Processor: Intel(R) Core(TM) i7-10700T CPU @ 2.00GHz Storage: 595.2 GB Installed RAM: 16 GB (15.7 GB usable)

Other people have also reported similar things over on Reddit with regards to Firefox and YouTube.

PLEASE TELL ME WHY THIS HAS BEEN HAPPENING TO ME FOR THE PAST MANY WEEKS!! HELP'

In my Task Manager, it shows 19 Firefox apps open?? I only have to Tabs open.

Thanks, I really would appreciate your HELP !!

Some web sites (Best Buy for one) upon opening go immediately to the bottom of the page. Anytime you search for something on those websites the page goes immediately to the bottom of the page and you have to physically move the page back to the top or beginning. It does not do this when using Microsoft Edge. Help!
