Updated firefox to 78.0.1 and now some websites aren't appearing in the drop down address bar. Before the update I counted 10 entries in the drop down menu and currently I'm at 8. However, if I enter the key "^" key I see the original 10. Is there anyway to make this original 10 appear by default?

After my browser being open for a while, usually a few hours, Firefox starts to get some major hanging in some tabs; I can have two windows open, one with a youtube video playing and another with like reddit or something else, and when browsing reddit, I get major hanging when interacting for around 7 seconds.

I recorded a couple performance profiles to see what's causing it, and it seems to consistently be a very long JIT or GC call, also labelled as "Cycle Collection" in the waterfall view.

I saved the profiles and I can upload them, but I'm not sure if they come with any private info so I'm reticent to add it to this thread.

I've watched the Task Manager (the Firefox one and the Windows one) while this is happening and memory usage in the Windows task manager seems to rise quickly over a few seconds then suddenly drop back down. I'm not sure if that's relevant. In the Firefox Task Manager I didn't see anything particularly salient other than energy usage spiking up just after the hanging is over.

This doesn't only seem to happen on Windows because it also happens on my Linux laptop occasionally as well, in a very similar manner. I didn't collect any evidence on Linux yet.

This has been happening for quite a while now, on multiple versions of Firefox in a row. I'm using 79.0b3 Developer Edition right now on my Windows machine.

Closing and reopening Firefox usually causes things to clear themselves out and I don't get such long hanging for a while.

I would expect JIT and GC to happen in much smaller chunks to avoid hanging, it's strange that it takes that long for one call.

Firefox 77.0.1 (64-bit) for Ubuntu

When I click on the chat icon in the old Reddit, it doesn't load. It loads fine on the Redesign. It works fine on both old Reddit and Redesign on Chrome, and another Reddit user has confirmed the same experience.

I see this version was updated on June 3, 2020, and while I don't use chat very often, I know it has been only recently unresponsive. Problem is, I use old Reddit almost exclusively when I'm actually using Reddit because I prefer the way it runs.

Hi there,

Firefox has started crashing anytime I try to playback media with my Focusrite interface selected for playback. This issue has been ongoing for a few months. Any page like youtube, with video or media embedded causes a crash.

For reference, I'm using a Focusrite Red8pre on a Macbook Pro. The error does not occur when using the laptops speakers for playback.

Any help here would be appreciated.

Cheers, -Harry

So for example, I have https://open.spotify.com/collection/tracks bookmarked. Pretty much every time I want to open that link, whether from top sites in a new tab or if I search that bookmark from the URL and click it, nothing happens. It will, however, work the second time I click it. It seems like really odd behavior.

I am running MACOS 10.15.5 on a MacBook Pro. Up until recently Firefox has worked perfectly. Now, and for maybe the past week or so, I get the pop-up error message "Firefox.app" can't be opened. No other indications or messages.

I have removed and reinstalled the app from the Firefox 77.0.1.dmg file. Still have the issue. I get the same msg when attempting to start Firefox in safe mode. I thought at first this issue may be due to the upgrade to 10.15.5 from 10.15.4, but a family member's Firefox works perfectly on 10.15.5. I actually don't remember when the jump to "5" from "4" actually happened. I have checked the forms and found nothing relating to this specific error. Perhaps I missed it.

I have attempted to recover Firefox from an earlier (6/2/2020)Time Machine backup which I believe was prior to the "5" upgrade, but the message is still the same.

Any help/suggestions would be appreciated. Thanks.

Did something change in Firefox today? I tried to let Firefox save a password and user name for Ask LibreOffice and when I tried to log in the password failed and I had to reset it.This happened again just now. (LibreOffice again). Firefox used to mess up in this way but that was ages ago. Everything has worked beautifully until today. Thank you!

OK sorry about not getting right back, I ask for help then I don't follow through not the best way of doing this. So I have done some more exploring on this problem. I am not sure what's going on. So I am running dual display on a laptop running windows 10 . Seems to me everything is updated. So up on the main display (external display) it's OK everything seems to be great on it.

So if I go to the laptop display that's where my problem is. So what I have done is on max the window is where I get this problem. Min. the size window goes away if the screen's location is about 1" down from the top of the frame on the screen. If I move it up some just a little 3/4" it seems to be a small drop down window again. If I move it up even more not to the max but just up to say about 1/2" the drop down window gets bigger however it is still cut down with no way to scroll down to see the rest of the window. So what my thoughts are is the over scan of the video is too big? If so how do I take care of it? I hope this helps out. Let me know thank you for your help on this matter. So if I go to single display its all good on the laptop window.

UPDATE: So I have also played with other web browser, Chrome and Edge and I can't recreate it in those browsers. I adjusted the over scan so its not that. I can't get full Images of both displays at once to big of file.

Hi, I am trying to run Rosetta Stone on my desktop. It only refers me to the mozilla blog page, but I cannot find what I need to change to allow the program to work. Help!

thank you!

I have been unsuccessful in downloading the American Airlines AAdvantage eShopping extension from the AA.com website. Each time I get the error "The add-on could not be downloaded because of a connection failure".

Firefox 79ob3 Window 7

Thanks

When I am playing media in a tab (youtube, spotify, etc.), if I open a new tab + website to browse, the audio/video in the other tab stutters badly.

This happens no matter what. With add-ons enabled, with ALL add-ons disabled, AND with firefox in safe-mode.

I have uploaded a video of the problem in action:

I have had the following issue 5 times now over a longer period of time (Windows 10, Firefox 77.0.1 and earlier versions).

Rarely, when I want to start Firefox, I get stuck in an infinite loop. The mouse cursor changes to a "loading" cursor and starts flickering forever, trying to start Firefox. This is bad enough for my whole system to behave strangely, e.g. mouse clicks will randomly not register or release.

Upon inspecting the task manager, I find that `consent.exe` repeatedly pops up and disappears. I assume it crashes and then firefox tries to restart, repeating in an infinite loop ... I only recently found a dubious/hacky way to stop this without logging out or restarting my pc: When I forcefully rename `C:/Windows/System32/consent.exe` via console, e.g. to `.../consent.exe_`, Firefox will crash "properly" with an error message and I can rename it back.

I have no idea what this `consent.exe` does or why it is called, which makes finding the cause or fixing the issue very hard..

Details / attempted fixes

The most recent time I had this issue, it appeared after trying to open an external link while Firefox was open. Firefox then found a new update and started automatically updating to the newest version (77.0.1), before trying to open the link and giving an error message (I don't remember what it was..). To properly apply the update I closed Firefox, tried to open it again, and I started getting this infinite crash loop.

This is not the first time I had this exact same issue, but the cause seems to vary. The first time I encountered this was back when there was a buggy Windows update, which if I read my logs correctly seems to have been at the end of February 2020. As far as I can remember at this time, the issue appeared immediately after restarting my PC and updating Windows (no opening of external links involved). The only way I managed to fix it was by uninstalling that Windows update. I disabled the following updates for some months. At this time I assumed the cause was the buggy Windows update, but since then I had the same issue 4 more times. Of the times I can remember the issue appeared immediately after

• updating windows
•  ??
•  ??
• clicking an external link
• clicking an external link > automatic Firefox update > restart Firefox > crash

Every time I got this issue I tried many things to fix it, including

• restarting Firefox
• restarting the PC
• deleting my Firefox profiles in `%AppData%\Mozilla\Firefox\Profiles` and `%AppData%\..\Local\Mozilla\Firefox\Profiles`

none of the above worked any time I had this issue - nonetheless the issue would disappear randomly without me knowing what fixed it.

The first time when it was seemingly caused by the buggy Windows update, I even uninstalled and reinstalled all of Firefox, including deleting my Profiles in AppData. Even then, the issue persisted on a completely clean and barebone install of Firefox. However, since then it is seemingly caused by opening external links and the problem always randomly disappeared before I got to try a clean Firefox install.

The most recent time, the issue disappeared while I was trying `firefox.exe --version`, `firefox.exe --help` to find out my Firefox version (I don't know the correct commands, so nothing happened). This did not work, but when I then tried to start Firefox again, I got about 10 or so error messages on the first attempt (unfortunately, I don't remember the error message..), and then the issue was gone on the second attempt to restart Firefox.

One other random guess I have is that some of my about:config settings may be related, in particular I completely disabled any links from opening popups, be it a new tab or window. But this sounds really like a bug and I certainly do not want to undo this setting.

In the end I am not even sure if this is a Firefox or Windows issue, and I am also not sure what would be a better place to look for support. Should I submit the above as bug report?

I am also very reluctant to try to reproduce the issue since I have no idea what the fix is and spent hours on it every time.

I do not get the speed I should which is 150Mbs since mid April this year I was gettin the speed before Then i changed to chrome and when I test the speed is 185 Mbs everytime. Right now I have reinstalled the fire fox and tested with both Ookla and fast.com both are giving a reading of 37.6Mbs on the fire fox and 184 on the Chrome. I do like fire fox but if the speed is not there then i do not want to use it. I am not good at this computer stuff so if there are any instruction please use simple terms, also I am too old to learn . thanks stay safe

I bought a new PC recently, which includes new hard drives and everything. Sync was always turned on on my old PC that I used until I switched to new one completely. And now when I logged into my Firefox account and tried sync, to my surprise, NOTHING synced. I've lost all of my saved passwords and bookmarks that I've been storing for years literally. Please tell me that there's a way to get those back somehow?

I recently switched from chrome to firefox. Normally I receive notifications of texts/imessages and calls in the top right corner of my screen even when I am watching videos in full screen; however, after switching to firefox I have noticed that sometimes I do not receive the notifications if I am in full screen video mode. This is causing me to miss some important messages. Is there a way to ensure that notifications such as imessages display even while watching videos in full screen?

When I m using google doc or sheet to edit a document from google drive, I notice that my cursor will freeze for 5-10 sec from time to time. No issues with chrome on the same documents. I never had this problem until the firefox updates in the past few months. I have tried the usual steps such as disabling all plugins, start firefox in safemode but nothing works. The problem is consistent across all documents, even for new documents. Does anyone know of a workaround?
