Firefox Support Forum

I am unable to open Gmail in Firefox. This has only just occurred - until now it has worked perfectly. On trying to open Gmail I now get the following message.

"Corrupted Content Error

The site at https://mail.google.com/mail/ca/u/0/#inbox has experienced a network protocol violation that cannot be repaired. The page you are trying to view cannot be shown because an error in the data transmission was detected.

Please contact the website owners to inform them of this problem."

No other site has been affected, and I can still open Gmail in Internet Explorer, {but I prefer not to use IE for emails

Any help solving this would be really appreciated

Since yesterday, Youtube hasn't been working on Firefox. The page loads, but then the video itself just won't play. The black screen comes up and then a circle, saying it's loading but it just never does. I've tried:

- Using Firefox in safemode, which caused YouTube to work again. I then re-entered the normal mode an disabled my only add-on (AdBlock Plus), but YouTube still didn't work. - Deleting my cache/history - Doing the windows+r thing, and deleting temporary files, which someone else on the website suggested - Refreshing Firefox

None of these solutions have worked. On my 'plugins' section, Widevine something and OpenH264 something will be installed shortly, but I don't know if that'll change anything, and it's been saying that since yesterday.

Hi,

Where does Mozilla Firefox saves the files from add-ons? Don't know if it is from Windows update or from Firefox update, but my add-ons settings keeps on resetting and I lose a lot of data from them because of that. And if I know where Firefox saves those files, then I can make a backup for them.

I suddenly can no longer view PDF files in Firefox. I get the message, "It appears you don't have a pdf plugin for this browser. Please use the link below to download this pdf." Firefox's troubleshooting info about disabling extensions did not help. I have no extensions enabled now. I changed my security settings on Firefox a few days ago to prevent sites from tracking me, and today I went back and reversed that, but I still can't open or view PDF files in Firefox. Thank you for any suggestions you can offer.

Im In a difficult situation, I have updated firefox to the new version 2 weeks ago. This version disable my 'session manager' add ons, without my knowledge. Yesterday I closed my firefox with 150 tabs and shut it down, hoping that when I start firefox again today, and click on 'restore previous session' that my 150 tabs will appear before me like they normally do. Except what happened was that I opened firefox, the main page opened, and before I was able to click' restore previous session' and restore my 150 tabs, I accidentally closed the firefox window. I then reopened firefox again, and clicked 'restore previous session' and all it would do is open the main window, and all my 150 tabs are lost now. I thought i shouldnt worry, because I did see an article last year about how to restore the firefox session that existed before the previous session, and there was something in that article about a sessionstore,js file and a .bak file that needs to be renamed. I went to my Firefox Profile Folder, there I clicked on the 'Sessionstore-backups' folder, and found these files:

1.previous.jsonlz4 2.recovery.jsonlz4 3.recovery.baklz4 4. upgrade.jsonlz4-20171002220106 5. upgrade.jsonlz4-20171024165158 6. upgrade.jsonlz4-20171112125346

I saved a copy of these files in My documents, but I dont know what to do with these files, I tried to rename the .baklz4 file to sessionstore.js, but it didnt work, I tried renaming it to recovery.jsonlz4 but it still didnt work, It is 23rd november today and I have given up hope that I would be able to recover all 150 tabs from yesterday, but the file in point 6 which is called ' upgrade.jsonlz4-20171112125346' seems to be a backup file from 15th November, so I thought Id try and rename this file and recover my tabs from 15th November instead ( about 120 tabs in total). I have tried renaming this file to , recovery.jsonlz4, previous.jsonlz, session.jsonlz4, sessionstore.js, but everytime i restart firefox, it doesnt read this file, and gives me that one blank tab instead. Can anyone tell me how to restore the 15th November file and how to load the 120 tabs in that file please?

Thanks

Hi,

Recently large file (90+megs) downloads keep failing . The download started normally, downloads for a little, then idles out and fails with no error messages. I'm currently on Windows operating system and i even tried disabling all add-ons and scan functionality in my browser and it's not my IPS giving me grief either. I've also tried with other browsers such as Explorer and chrome and have no problems with them with the same file and location.

Any help would be greatly appreciated, this is getting really aggravating...

Thanks, - Ult

How do I restart firefox with the same tabs and windows?

It isn't in the File or Tools menu. I get nothing when searching help. Yet FF knows how to do it, say when updating extensions.

I know I can do it by saving my session, exiting, restarting and restoring the session But is there a single command to do all that?

Thanks. --David

So i was watching a video on youtube as a game had frozen, decided to open task manager to end task for the game, then noticed there were 5 processors of firefox running, just wondering why are there 5? all i was doing was watching youtube.

below is the message that I get when I try to open my portfolio in yahoo finance, I am using Firefox as my browser

"The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies."

HOW DO I FIX THIS PROBLEM....THANX

Couldn't open original download ("Blocked Publisher" notification). This morning, I received a second notification from a different URL. Smells like a malware scam to me.

I recently uninstalled Chrome and the default browser set itself to Edge (YUK!!!!) when I try to set the default browser to either Firefox or Firefox Developer I can't .... because there is no option to select Firefox

Every time I try to view an MSN or Amazon video, I get the sound but a GREEN screen and no video. I always have to go to another browser to view content. WHY IS THIS HAPPENING????

Hello,

Thank you

Don't know how it arrived there, but this bar is blocking the tabs of Firefox when I'm browsing. It's a single line bar which would, if I ever wanted to use it, allow me to search the web via Chrome. But, I don't! My Firefox screen used to fit below this bar, but that, too, has changed, somehow. Seems the gremlins are in there! And... when I open Word, or Excel, the top line of tabs is also, now, hidden behind the Chrome bar. Making it a real pain to do anything. Yes, this Chrome bar is there with every application, whether Firefox is open or not. I would greatly value any contribution that will rid me of this extremely irritating issue. I tried to upload a screenshot to show the offender in situ, but the flower petals are still spinning after 30 minutes. so posted it as is.

This is a recent problem I never had before. Flash videos on any website, even youtube, endlessly buffer and never play. No problem playing on Chrome. This is on my toshiba laptop (windows 10), no problem on my desktop computer (windows 7) My Firefox version is 54.0.1 64 bit My flash version is 26.0.0.131 Flash is set "always activate" in options. No message comes up and no security warning next to the URL Tried updating flash, no change. Tried giving the page the permission to allow flash instead of default by clicking on the green lock and changing that. What to try now?

(Also tried to upload an image on this page, and it seemed to be endlessly bufering as well, not sure if it will work or not, so I am just going to hit submit whether it does or not.)

I have tried a lot to remove Lavasoft Ad-Aware secure search from my browser but I am unable to so. I have received this adware from uTorrent application. Please help me in removing the extension from my Mozilla browser as it's like Hijacker and making me worried. And it's a security flow in the Mozilla Firefox and many people have problem in dealing with this.Please check the below links about my problem that I want to convey.. 1) https://www.bugsfighter.com/remove-adaware-secure-search/ 2) https://forum.adaware.com/index.php?/topic/33145-getting-rid-of-secure-search/ 3) https://support.mozilla.org/en-US/questions/1049990

All the above mentioned are very complicated for the user So I urge you to FIX this Issue as early as possible. As it is very annoying to have a unknown search engine without your consent. And Let me know as early as possible.

I'm having the same issue described in this thread: https://support.mozilla.org/en-US/questions/1147868 and have tried the recommended fix. I have changed the setting reccommended in about:config to false, but about:support still shows 1/1 for multiprocess windows, and I have 6 instances of Firefox running in the process manager (screenshot shows 5, but it has been as many as 7 at once).

Is there anything else I can try to fix this issue? Any help is much appreciated!
