Firefox Support Forum

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

Today Firefox stopped altogether and dimmed the entire window and popped up a "Try the Firefox VPN" message. I use Firefox specifically to get away from disruptive, intrusive violations like that. This needs to be removed immediately and never ever happen again. It's completely antithetical to the core values of Firefox.

Furthermore, several users have reported it breaking their browsing. See this Reddit thread:

https://www.reddit.com/r/firefox/comments/13rnt88/why_is_firefox_windows_11_version_showing_me/

This affected me on Windows 10 running Firefox 113.0.2 64 bit.

I've just installed Firefox 113.0 and my tab bar is now above the toolbar and bookmarks bar. Up until 112, the tab bar was below the bookmarks bar. I have no changed anything in UserChrome and in fact that file is still dated 2020. I've searched but haven't found an explanation. Anyone know what changed or is this just a bug? Thanks

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

I've tried everything to fix poor picture quality when streaming "third party" videos, e.g., YouTube. Colors are washed out; weird contrast; everything looks like it's coming through a haze. Streams from Netflix, Amazon look normal. And sorry, guys, the same third party streams from YouTube et al. look totally normal in the MS Outlook browser. Have tried all kinds of settings and rebooted as well. No change.

Please advise. This problem appears to be unique to Firefox.

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

I have seen multiple copies of this question, some unanswered, some with the same "answer". All the questions are closed so I cannot reply to them. The "answer" does not work.

I have the "Show tabs from other devices" sidebar. I also can access from "Open application menu" > email address > list of synced tabs. Both methods show me the device name and all of my synced tabs. Neither method has an "open all tabs" option. If I right click my device name nothing happens. If I right click a tab, it opens that one tab. I don't know how many tabs I have on my Android. I have enough tabs that it only shows the infinity symbol instead of the number. It has shown the infinity symbol for a long time and I've opened many more tabs since. It could be hundreds or even thousands of tabs. I have 224 tabs on my laptop. I want to open all 224 laptop tabs plus all however many Android tabs on my laptop at the same time. I'm aware this will cause significant lag on my laptop. I'm not looking for a solution for that or people telling me not to do that. I want to know how to open all of my synced tabs at once on my laptop, without having to click through one by one.

Edition Windows 11 Home Version 22H2 Installed on ‎2022-‎09-‎21 OS build 22621.1702 Experience Windows Feature Experience Pack 1000.22641.1000.0 "You're up to date Last checked: Today, 17:15" (Just clicked "Check for updates")

Firefox 113.0.1 (64-bit) "Firefox is up to date"

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Till version 112 I used this in my userChrome.css to get back the close buttons on tabs, but only when I hover over them (active or inactive tabs): .tab-close-button{ display: none } .tabbrowser-tab:not([pinned]):hover .tab-close-button{

   display: -moz-box !important

}

But now with version 113.0.1 it doesn't work at all and no X appears when I hover over my tabs.

I tried adding #tabbrowser-tabs[closebuttons="activetab"] on top of the previous code, but it made the X appear all the time.

How could I update this code so I get the desired result only when I hover over a tab?

Hello. When I paste something inside firefox, then firefox suddenly shuts down and after that a window pops up, informing me that firefox has crashed and asking if I want to load the previous session... No changes have been made to my computer lately. Firefox has been updated to 113.0.1 but the problem has not been solved. Any suggestion?

Thank you.

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?
