Firefox Support Forum

Hello, recently I have been getting this message a short time after opening Firefox. It looks like the attached picture. Based on what I have seen, crash reports can help get to the root of the problem, however, Firefox doesn't seem to be generating crash reports after these tab crashes. Can anyone help me with both of these issues?

I recently reinstalled Mozilla and I can't drag and drop new bookmarks, nor can I import my old bookmarks from an HTML file. If I drag and drop a tab to the bookmarks area, it just opens a new browser window.

I have no add-ons installed, I only use AdBlocker, have been for years. I've restarted in safe mode, same thing.

When I click import from HTML in the Library, they appear in the lefthand column in a folder called Bookmarks toolbar. I just can't drag them to the browser toolbar, where they used to be.

Earlier today I updated my copy of Firefox on a Windows 10 PC to the new 64 bit version of Firefox 55. Since doing so, all of my bookmarks have disappeared, and newly created bookmarks are not displayed in the browser.

This is regardless of whether the bookmarks are imported from .html file or other browser.

I have since re-installed Firefox and it is still the same after having deleted personal settings and changed some settings as recommended on the help pages.

But I still have this issue: : I have never encountered this problem before.

Can someone please advise? The PC concerned runs Windows 10 and has 8GB RAM with more than adequate hard disk space available.

Mr Morgan.

When I started my computer today everything on firefox was gone: my history, my bookmarks my downloads. I can not recover the bookmarks. When I try to recover the bookmarks a dialog box opens that says it is unable to process these request. Please help!

Firefox tab crash a lot since I upgrade to 53.0.3. No problem before. Now firefox crash a lot on youtube or any kind of site with embidded video/flash player. 27 crash in 1 hour of testing after this i have given up and move to chrome who doesn't crash.

Please help

Since my laptop, running Windows 7, updated today to Version 55, I have lost all my bookmarks. Trying to restore them using "import and back up" has not worked. I can see various dates of previous back ups, but when I try to restore I always get the "Unable to process the backup file" message. Also, and maybe more concerning, I can now not get Firefox to actually brows. Once I type a URL into either a new tab or my homepage and press enter, not happens at all. The only site Firefox will now access is my homepage, which is a Hotmail account. Prior to the update, I had not changed any settings and the only add-on I was running was an ad block I have used for some time. I have disabled the add block ad on, and I have reinstalled Firefox to try and resolve the problems with no success.

...I upgraded my Firefox browser today to version 55.0, but when I restarted it, it wouldn't access any of the details of the Profile I use all the time... I have looked repeatedly, and there is never any History, either pre-existing, or newly created, and my Bookmarks and Fast Dial add-on aren't available... When I try to log into a site, however, it still remembers my Password data, and that is visible in the Options : Saved Logins popup... I had a similar experience with Firefox Developer Edition, and I finally gave up, and switched to regular Firefox, but I'm now running out of options!! I am running Windows 10, on a Laptop with a 6GHz processor

My Firefox is always crashing when I try to view videos, especially when I try to change the time in the video. It crashes the tab, and then takes down all the other tabs with it.

I've done a virus scan, clean install, and tried running in safe mode. Made sure all addons are up to date and tried with or without flash. Nothing works. This has been going on for a couple of weeks now. I have Firefox 55.0.3 (64-bit).

I used the site every day in the last 2 months and all worked flawlessly until the last update. Now when I go to another tab and then return to the S&F one (https://w18.sfgame.net/), the whole screen becomes non-interactive - I cannot press buttons on it or do anything and only page refresh works. Also happens when I right click and open java settings. I am using the latest version (55.0.3) but am experiencing the issue since 55.0.2. Any help would be greatly appreciated, as Firefox is my fav. browser and I wouldn't like having to revert to Chrome again just because of this - it's really ruining my experience :(

Thank you

Only add-on is Norton Security Toolbar, which is now disabled. No extensions. Only Plug-ins a Codec, Widevine, and Shockwave. NO changes, no updates, I suddenly lose all my bookmarks...even-right clicking the back arrow button reveals nothing, even though I can left-click and backup one page at a time. I tried running "Verify Integrity", and it tells me "Unable to check database integrity". I tried to Restore all of my existing backups, each one says "Unable to process the backup file."

Would ALL of my backups become corrupt on the same date? My assumption is that Firefox has lost it's ability to read sqlite files. Is there a quick fix for *that*?

The *first* symptom was that Firefox suddenly started "grinding"...even the "waiting" circle in the tab grinds to a complete halt, constantly, and it won't respond to *anything*, despite the fact that I *never* get a "Firefox is not responding" message. Ever. Disabling Norton didn't help that, either.

I downloaded Firefox today and I'm trying to install uBlock and Zoom Page WE. I can install them just fine and their buttons will show up in the toolbar. However, if I close Firefox and open it again the buttons will be gone and the addons will only work in websites I had visited before restarting Firefox. They still show up in the addons menu and the buttons will show up again if I deactivate and activate the addons but as soon as I restart Firefox the buttons will be gone again. The addon buttons won't show up under the personalize menu either (even though I can move them there before closing Firefox).

I used to be able to watch the National Zoo panda cam for years - https://nationalzoo.si.edu/webcams/panda-cam. About April it stopped working. It worked for 2 days earlier this week (8/23-24/17) until I installed the latest Firefox update. Why can't I see the cams any longer on this website. I get this error on many websites; videos won't load or won't play. This same error also stops videos on the CNN.com website, which is actually appreciated. I did try turning off the IPv6 - that did nothing for me with this problem.

I am running Windows 7, my computer is within 4 years old, no problems seeing the other panda cam pages from the San Diego Zoo or Zoo Atlanta.

It seems this site is unable to upload my screenshot of the page and error message. Bummer!

THANK YOU for all your help!

After upgrade to 55.0.3 I can no longer download .acsm.

1 This problem is only occuring on 1 site. (EBSCO). I checked if I could download .acsm file type from other sites e.g. proquest, and all good. no issue observed.

2 No error message is returned. I just donot recieve the .acsm file even though I have clicked download.

3 If I use safari I can download the .acsm from ebsco site, no issue. (This is how I borrowed the ebook today I needed.)

4 before upgrade to 55.0.3, I downloaded .acsm from ebsco site with no issue.

FYI: .acsm file type is the Adobe Digital Editions file that allows you to read the ebook in ADE.

What has changed that would be stopping this? The files are very tiny. Any ideas?

thankyou for your help.

Every time I play a video (YouTube or otherwise) or even play music on Firefox, ever since I got a Firefox update today, has caused it to immediately crash. Is there anything I can do?

I already deactivated all plugins and add ons. I even reinstalled firefox but it keeps crashing. ID: 2b0b0a58-6c28-40b1-bc2c-37a5d1170911

If it is my virus scanner that causes it what would I have to do to prevent it? It's a company laptop and I can't deactivate the virus scanner.

I'm having all sorts of problems after Firefox automatically updated to 55.0.2 in Windows 7. It wouldn't run. It would start the service but would never actually open/launch the app. I uninstalled it and went to the 32bit d/l page to reinstall. But, it installed the 64 bit version (grrrr). Now, the biggest problem I am having is that when I click on a link in an email or office document, the browser doesn't launch or a new tab open. Instead, I get an error message: General Failure. The URL was: http://www.URL. Application not found.

Firefox is set to my default browser.

Any ideas?

Firefox magically stopped working tonight. Based on reading help files and past forum posts, here are things I've tried with no luck:

Note: Running Windows 7

- Rebooted (of course) - Uninstalled through the task manager and reinstalled. - Uninstalled and deleted the C:/Program Files/Mozilla Firefox directory and reinstalled - Once reinstalled, attempted to start in safe mode via holding down Shift while loading - Attempted to start in safe mode by attempting to type many things in the run window:

        Firefox -safe-mode
        Firefox /safe
        "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

- Attempted to add a new profile by typing in the Run window (after reinstalling):

        "C:\Program Files\Mozilla Firefox\firefox.exe" -P 

None of these solutions have had any results. No matter what I do, no Firefox related windows will come up and I get no error messages of any kind. Most of the time I at least get a busy cursor for a second and a firefox.exe process will start. I've kept the Task Manager open through most of the attempts and killed firefox.exe between all different attempts. Most everything I do will still open a process (I have two of them still running right now) and I kill all of them in between attempts, not to mention shutting down. I even did a hard battery pull on my laptop just to be sure. I'm not making any headway. If I could at least get an error message that would be nice, but I get nothing at all. Any other suggestions?

My firefox seem to be updated for some reason (version 55.0). All of my history, session and plugins disappear. I check the profile directory and it seem to be the old one. Because there're bookmarkbackups, extensions and sessionstore-backups in there (and profile's date created is 2015). So I come back to check the addons list in Firefox. It's still there with freak 'LEGACY' in yellow background so that I suspect my firefox is updated and check the version and release date. My gmail still login+other email profiles are in the list.

Please help me to restore the data 1. bookmarkbackups: I make some search about this topic and restoration; It's fine now. 2. session: How to restore my session back? 3. add-ons: any add-ons that I'm using before still Enable and some that are disable is correct there. But I don't see any add-ons. Adblock Plus, Firebug, Geasemonkey and etc. Icon are gone. How can I use them? 4. Are there any data that need to be restore and can you guide me about it?
