I searched for a fix, it says (from 2016) if you are using 64 bit firefox you must switch to 32, beause the flashplayer for 64 bit firefox doesn't support Context3D. But that is completely irrelevant because I am using a 32bit firefox and getting the error. from what I've searched it's not flashplayer causing it. and I have just installed the newest flashplayer.

OK so since I wasn't able to find a solution here and wanted to share the solution I found since so many folks seem to be having this issue despite so many of them being 'resolved' and 'archived' with non satisfactory solution, let me share what I found. This applies for those who have already tried these steps:

- If you can access the site that gives you this error in Firefox but no issues in another browser; - If you've cleared the cache and you still get the error; - If you've deleted all cookies and still get the error; - If you've tried starting Firefox in Safe Mode to temporarily disable your addons and still get the error,

Try this: - in the address bar type "about:serviceworkers"; a whole list of these hidden code/cookie snippets should appear in the page. I was shocked by the shear amount of them and their privacy implications >:-( - click "unregister" to remove them one by one - restart your browser.

After restarting, the problem disappeared. In my case, a corrupted 'serviceworker' was preventing me from accessing gmail.

Upon further reading, one learns that it's some kind of cache and that it helps accessing websites. Also, that it gets rebuilt as required. Finally, that this 'feature' can be disabled by turning the about:config value dom.serviceWorkers.enabled to false.

Hope this helps someone, and sorry if the formatting looks awful, I have no idea why my bulleted list doesn't show as it does in the editor.

I run v51.0.1 DELIBERATELY because you keep making changes that I canNOT undo! Today half my ad-ons that I have been using for YEARS became disabled. I don't care WHO thinks they are "old" or "unsafe" - THIS is why I have stayed on v51 so I can work with what I need instead of what you THINK I need. I need the config parameters to turn OFF ANY and ALL of your "protections" that I do not need You have 15 versions of defective software now, you had 14 until you screwed with mine. A "feature" without an OFF switch is a defect and I want this defect corrected. I do NOT want to update to 65 - I lose too many features I want to keep and the add-ons I want to keep will not work in v57+ - Hence I stayed at v51. --Kindly tell me how to repair my now-defective browser and then please tell your developers, as politely as you choose, to STOP ADDING DEFECTS! A "feature" without an OFF switch is a defect.

Thank you Richard Hill

Hello I have some older cisco CDs, where, except for the 1st home.htm, ALL the .htm files on it are zipped. Cisco started doing this, to save space back when a HDD was less than 1GB, back about 1997. After this, all the Documentation CDs had to be run/viewed thru the AUTOPLAY.exe 1st, then 'Launch CD' (which ran LAUNCHIT.EXE I think) which put an unzipper in memory so that whatever browser you chose (on the next screen) woudl have every .htm file unzipped b4 it was passed on to the Browser.

What I want is to copy the ENTIRE CD to my HDD and view it w/o using the CD.

So, what I need is a Plug-in or ? so I can unzip all the .htm's within Firefox.

I've tried posting some messages to 7Z about copying the entire CD to the HDD all the while unzippign .htm's on the fly. I was told 7z can't do it.

I used to program in C, do I have to write a program to do this ?

Seems simple enough... - find all .htm files below a certain Directory, and unzip them, using the same name, appending a unique number or letter (like -old) to the filename as the new unzipped file has to have the same name as the original.

Simple. But I haven't programmed in decades and don't even have a compiler on my PC, yet :)

Can someone tell me the difference between show all tabs from last time and load tabs. I'm trying to figure out why Firefox slows down and eventually crashes. I have close to 300 tabs but I have clicked on only a few. The rest I though were dormant. Still after a few days FF slows down. The last time I decided to restart FF I clicked on File and waited 17 minutes for the drop down menu that let me click on Exit. 23 minutes later FF crashed. So whatever is going on in the background has to be involved with why this is happening. The FF interface by the way had been closed for about 20 minutes before I got the crash notice. This is not about running MBAM,buying a new machine or upgrading to the ESR. to fix the problem. It's academic. i want to know why because all the recommendations to upgrade in the past have not improved the situation and recent upgrades made things worse. I will be doing the ESR upgrade in time but I want to be able to launch this version as well perhaps as a different user.

This seems to have just started and I'm not sure why. I'm using 2.0.11 which is suppose to work. When I clicked on the new tab button in the menu bar Firefox used to open a tab to the right of the one I was on. Now it has reverted to the old way of going to the end of all the tabs. Is it possible that the settings in about:config were changed by something I did. By that I mean I did not go into about:config and change anything, It would be something like clicking "view email in browser". Anyway if some one can point out the about:config settings I should review and how they should be set I would appreciate it. I'll start there, unless there is a known solution. Thanks

Hello,

I've installed VLC and didn't notice the VLC mozilla plug-in, so it replaced my Adobe Flash player. Since then every video I want to open it just opens in a new tab & without the frame-preview.

I've tried these steps: Uninstall VLC. Uninstall flash player. Re-installed flash player again.

After I've Re-installed flash player alone, Videos are still opens in a new tab. So how can I get flash player back as the default player, especially it disappeared from the list of options/applications, even webm (or something disappeared).

FF constantly takes more ram even when I'm not looking at a tab, I'm reading emails for instance. A quick look at task manager shows FF is still eating more and more RAM. Is there a way to stop websites from calling for RAM that they wont give back. I really don't want advertisers to keep asking if I clicked on there ad, especially when the tab isn't even in focus. Is there a way to put non focus tabs to sleep or something that will stop the RAM drain?

When I press CTR +SHIFT+B, I don't see any of my bookmarks or anything to left or right, its all white I can see the top headings though.

When I click Bookmarks (up top next to History, and Tools) I can see all my bookmarks, there are quite a lot. The problem happened after I had to power off at the electrical outlet and I didn't shut down Windows 8.1, and Firefox, because my computer had stalled overnight.

I need to see my bookmarks again when I press CTR + Shift +B

hello. my problem is related to the question: https://support.mozilla.org/en-US/questions/1158868https://support.mozilla.org/en-US/questions/1158868 i believe that there is a bug in esr version of firefox that causes that i cant open many https website and recieve secure connection failed error. or is there any setting (specific to EsrVersion of firefox that i should change to can open websites? my story as followes. i one day downloaded and used one vpn program, (dont remember openning these specific websites before using vpn when i installed firefox esr version. i cant open many websites that could open previously. for example: www.daumpotplayer.com www.bleepingcomputer.com www.howtogeek.com are just three examples and the numbers are more! i reset my dns settings in network connections and solved the problem temporarily. but the problem came back again after reusing vpn program again and did not solve until now. i uninstalled and reinstalled my firefox several times without any success. using safemode (with fresh profile) as i said: does not work, because (see my previous sentence.) dont suggest any antivirus or antimalware for me, because i dont trust such programs and never use them! so, my problem is not related to interfeering antivirus or antimalware programs and there false positive! i tested google chrome and chrome opened the websites without any problem, so it is firefox issue only. so, i tested the article https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can did not work for me when i changed the network.ssl options which are mentioned in the article.

i tested with several versions of firefox esr and the result was secure connection failed error message. firefox esr 45.9, 52.4, 52.5.2, 52.6 and 52.8, so i am sure that there is a problem in esr versions of firefox that should be fixed, or a unique about:config setting (present only in firefox esr versions, not regular versions) that should be change by user to resolve this issue. i wished and decided that use firefoxEsr 52.8 forever, but if the problem cant be fixed, i should firefox 51 and use it forever without update!

because when i installed firefox 51, could open all the websites without any problem and my firefox now is even faster and more responsive than esr version! i thaught that firefox esr should be more stable, trustworthy and less error! by the way, i use firefox 32bit version on windows xp.

Hello, I have no problems printing with all browsers.... except FireFox. In Firefox, I can only print the first page, and I get a blank page1 and blank page3 (with page2 containing the first page). I try to emulate the print view, but it shows ok. I am not sure how I can resolve my issue as the CSS is enormous. I would have to visit refactoring a bunch of css and that is a project on it's own.

This is frustrating, as I'm currently letting people know they should use other browsers.

All other browsers print properly, but when they don't, I use the emulate print view (css) and I can then debug it. But I can not do anything with this. Here is an example page I found that shows the problem. Print,.. issue, print emulate... no problem...
