Firefox crashes and can't use the existing profile when relaunching

Over the past week I've had this error popup a few times when Firefox is launched:

"You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I haven't yet spotted a pattern, but the most recent time it happened, I had the browser already open and either opened a new window or clicked Firefox in my start menu. The new window showed my homepage (blank tab) but was unresponsive: I couldn't type into the address bar, click a bookmark, or even close the window. The existing window was fine, so I closed that but had to kill Firefox in Task Manager.

When I relaunched Firefox, I got the above error message. Luckily I use Sync, so my many bookmarks are backed up. But of course all cookies have been deleted, so I have to login to websites again.

Firefox is up-to-date (84.0.1, 64-bit) and running on Windows 10 Enterprise. I even uninstalled, cleared out the data in AppData\Roaming\Mozilla (plus Local and LocalLow), and reinstalled.

As I said, this has happened a few times over the last week (3 or 4?) and is starting to get annoying now!

Any ideas? Thanks!

After installing the DRM content through the browser I still cannot play any videos on Netflix or Udemy.

I have run this website (https://www.jeffersonscher.com/sumo/html5-video.html) from previous answers to check and the results are attached to the question.

I have also checked media.eme.enabled and it is set to true.

I am very much puzzled by this.

Firefox is persistently putting downloads in the wrong location (1-16-21)

I am currently on Firefox 84.0 on Windows 10.

Every time I download any type of file, Firefox puts the file inside of (C:) > Users > tmmor > AppData > Local > Temp. This is extremely frustrating because I have to manually move the files to my 'Downloads' folder every time I download a new file. I have changed my settings numerous times. In Options > General > Files and applications. I have selected the "Save files to" and I have changed it to many different locations and my files still end up in (C:) > Users > tmmor > AppData > Local >Temp. I have even resorted to selecting the setting "Always ask you where to save files." After closing and reopening the browser, I try to download something and Firefox never prompts me to select a download location (Contrary to my settings). Firefox just automatically downloads the file and puts it in (C:) > Users > tmmor > AppData > Local > Temp.

After looking for solutions online I have went into "about:config" and I found out that "browser.download.dir" was already set to "C:\Users\tmmor\Downloads" (My intended location) and "browser.download.lastDir" was already set to the same location. I have also set "browser.download.useDownloadsDir" from false to true. Firefox still puts my downloads into (C:) > Users > tmmor > AppData > Local > Temp.

I am also the administrator on my device. I am not aware of any windows settings that are blocking Firefox from putting my downloads into my "Downloads" folder. Microsoft Edge and Google Chrome put my downloads into my "Downloads" folder every single time I download something, why cant Firefox do the same?

I also do not believe that any of my extensions or plug-in's are causing this issue, I have very few extensions and plug-in's.

Firefox is persistent at saving my downloads to (C:) > Users > tmmor > AppData > Local > Temp. I have never gotten Firefox to save my downloads to my intended location (The downloads folder). Can anyone please instruct me how to resolve this issue. This is my last resort to solving this problem, nothing has worked for me. Thank you for your time, this experience has been stressful for me.

I should not have to ask this, but somehow this essential feature has been removed *again*. How in the world do we view the URLs of links in Windows 10 now? The status bar has been totally disappeared, and although there are a number of add-ons, so many of them are about other kinds of status, or only show the URL in limited circumstances, that I'm having trouble figuring out which ones offer the basic view-URL-on-hover. Does anyone have recommendations?

Even better, who can explain why it's a good idea to make it hard for users to see this absolutely vital information? If security is important then it's important to make it easy for users to see where links go before clicking on them. Full stop. And even if the web were somehow magically totally safe, people don't want to waste their time and bandwidth playing guessing games. We want to know what something is before we bother to open it up. Why is that so very hard to understand?????

12/25/2020

Hello Mozilla Support, please advise on how to permanently disable the "expanding/enlarging" URL bar that continues to be featured with each new browser update. From previous experience, I have uninstalled/reinstalled and attempted to change the following advanced settings as seen on other threads:

Method 1: 1. about:config 2. browser.urlbar.openViewOnFocus = FALSE 3. browser.urlbar.update1 = FALSE 4. browser.urlbar.update1.interventions = FALSE 5. browser.urlbar.update1.searchTips = FALSE

Method 2: 1. about:config 2. browser.urlbar.disableExtendForTests = TRUE 3. browser.urlbar.maxRichResults = 0

Neither of these methods currently seem to work and even when they have worked in the past, why does Mozilla continue to enable this feature with each new update without a simple option to disable when so many users have requested instructions on how to shut off? What is the purpose of the expanding URL bar? What does an enlarged URL bar do to benefit the search experience? Is there another reason why Mozilla keeps this feature going for every new update? It often becomes time consuming to search and figure out what the new procedure is to keep disabling, every single time an update occurs.

Please help, Thank you!

Firefox prompted me to update. I did. Then I only had two choices: exit or create a new profile, and since exit did nothing but close the program, I did the second thing. Now all of my bookmarks are gone - that I rely on for work. I need specific step-by-step instructions on how to get those back. I looked through several of the FAQs on this and none where helpful. I did not have a Firefox folder put on my desktop. Losing these bookmarks will be a major issue. Please help!

Hi. The message "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks..." has appeared at the top of my Firefox window. I don't think it's been there for more than a couple of days, so it must have been added by a recent update. I already have my bookmarks available just fine, so is there a way to get rid of the message? Thanks!

For the first time after 10 years, I can no longer access my PNC bank account using Firefox V84.0.2. This problem started just this Sunday Jan 24, 2021. I am using AVG and the Defender firewall. When I try to enter my account PNC tells me that it cannot find the code and tells me to use another browser like Chrome or Internet Explorer which I don't want to do. PNC tell me to contact Firefox as, "It is not their problem." But so far I have found nothing in Firefox to solve the issue whatever is causing it. I need help as I would rather not change browsers.

I have restarted my PC, checked and restarted AVG, checked the troubleshooting program, and reinstalled Firefox, but nothing seems to correct the problem. So where do I go from here?

Hi community,

Somehow the Other Bookmarks folder showed up at the end of my bookmarks bar. I am pretty sure it was not there yesterday. I assume that somehow I accidentally placed it there.

The problem is that I can't either move it, or remove it from there. When you select it, delete option is grey and not available. Does anyone now exactly how to remove it from the bookmarks bar?

Thank you people... :)
