Firefox Community Forum

Files previously downloaded by earlier versions of Firefox as .webp cannot be opened by 115.19.0esr. Firefox keeps asking what application to use, and I have selected Firefox. When I OK the selection, it opens a blank screen with the same question (what application to use). This goes on forever, opening a new blank tab again and again, each with the same question about what application to use. My old Mac operating system 10.13.6 retains its original version of Preview installed, and of course, that version of Preview does not know how to open .webp files.

I've been a Firefox user for ages but in the last week I haven't been able to use it at all. Every time I launch the desktop browser it gives me a blank page. I can type in addresses but they never take me anywhere. No google. Can't access settings. Nothing. I've tried seemingly everything. Safe mode. Administrator. Deleted everything and installer at least 5 times to try and start from scratch to no avail. Tried Revo. Tried multiple anti-malware cleans. System updates. Tried using older versions of Firefox. Everything short of a factory reset on the whole desktop which I'm really trying to avoid. I've checked every Reddit thread and forum post I could get my hands on and nothing is working. Does anyone know how to get Firefox working again? I've tried other browsers and hate them I would really like to keep using FF if I can. Picture shows what the app has looked like every time I boot it up or try to search anything for the past week.

In the Firefox View tab, we can search for Open Tabs. I am wondering how I can make a strict search for a particular pattern. For example, let's say I have hundreds of tab open for youtube like below:

https://youtube.com/watch?v=<random> https://youtube.com/watch?v=<random> https://youtube.com/watch?v=<random> https://youtube.com <---------------------I want this one to appear in my search

how can I ONLY search for open tabs that is the youtube front page (i.e to not match anything after the ".com"). If I just search for "youtube.com", it will match all of them, but I only want the front page.

Then, i can quickly close all of the duplicate

For a few weeks, I've been unable to download Nightly updates via Help>About Nightly because Nightly thinks another instance is updating. I have found no solution or information on this issue. I never run more than one instance, though I usually have 50-60 windows open with many tabs each. Am I hitting a hard coded assumption that more than one instance is running if some number of windows and/or tabs is implying multiple instances? Nothing else seems to make sense so far... This issue just appeared one day; I recall nothing out of the ordinary. Was just trying to download the latest Nightly as I'd done for years and am now stuck with this issue preventing access to updates.

The Firefox software has been updated but no longer starts

Since the latest update my firefox seems to have trouble loading video and streaming resources. Browsing through youtube shorts it would not let me scroll down by using the mousewheel or have a delay of 3 secons from time to time. changing to the downarrow to view the next short made me hit an invisible wall at about 200 shorts. browsing twitch also leads to signifficant delays of several seconds until any click action is performed. one time it even crashed so i decided to clear the browser cache and restart my pc. is there a new way the temporary data is stored in the new version? i have 32 GB of RAM and lots of free disk space so that shouldn't be the issue. Firefox used to have no issues whatsoever in older versions regarding videos and streams.

Hi,

I have a dual monitor setup and quite often and randomly, when I launch the browser it opens on the secondary monitor instead of the primary, which is the one I always use. Firefox is up to date: 135.0 (64-bit)

I've read somewhere that I have to move the browser to the primary monitor, resize it so that it is not fully expanded and close. After opening it again it opens on the primary screen and I can maximize it and close again, but when I open the browser again the next day it may open on the secondary screen again... or not, just a very random thing. Any clue?

Thanks, Pere

Hi,

Out of nowhere, my history was deleted and I can't open previous windows. However, it does show previous tabs. This seems to happen periodically. Can you tell me how to address this?

thanks, David

This website has always opened in Firefox until the last couple of weeks https://www.tvinsider.com/tv-listings/?codeword=highwaypatrol

I have used Firefox for years, and especially since the ability to pin tabs was created. After this last update I experienced an issue on one website, which the tab is pinned, that was not present before. After putting things into my shopping cart, I click on the shopping cart and if the original tab is pinned then the shopping cart opens in a new tab. Before this latest update Firefox was smarter than that.

I can't sign into Sydney and I don't have a password so it says use the member ID number and I use it and it still doesn't work and I don't use the first three letters I use the numbers after that but then I have tried the first three letters also and it still didn't work

Доброе время суток!

это папка C:\Users\Илья\AppData\Roaming\Mozilla\Firefox\Profiles\v2zudvil.default-release\storage\to-be-removed постоянно растет, удалять ее приходится вручную, почему так происходит? и как это избежать 

последний раз, когда удалял, это папка занимала 52ГБ

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.
