Firefox Support Forum

Some webpages, that I must log in to, are coming up blank, when I attempt to login. No error, just blank white page. Two examples are paypal and textfree. I have cleared everything I can think of or find on the internet. I have refreshed and restarted several times. This has all started int he last few weeks. The two sites mentioned are ones I really need access to. I am not sure if it is my machine or the browser.

No way to ASK a question in the Monitor section, there is no GET HELP button.

Application error: a client-side exception has occurred (see the browser console for more information).

In general, getting to the "ask a question" button in the support website is like finding hens teeth.

Didn't there used to be a Discussions forum, where you could see all of the questions being asked?

Hello. I share the exact problem had by [[magicienne|https://support.mozilla.org/en-US/user/magicienne]] (posted 4/6/21, 4:08 AM)

I too, only have the choice of importing data into Firefox. Not exporting. I've version 78.9.0esr (64 bits) of Mozilla as well and work on an iMac OS X (El capitan). My desire is to import the information into Safari v15.6.1 installed on a MacMini v10.15.7.

I've read and followed the directions posted 4/6/21, 11:20 AM by moderator [[cor-el|https://support.mozilla.org/en-US/user/cor-el]] to no avail. The export function still does not show in the pull down menu.

•••••

The directions read: The export and import logins menu items aren't present in Lockwise in Firefox 78. • Firefox 79+ comes with an export to CSV feature. • Firefox 80+ comes with an import from CSV feature.

The LoginExport.jsm module is present in Firefox 78, but hasn't been enabled and you need code in userContent.css to get the export menu entry in the cogwheel menu in Lockwise. Add code to the userContent.css file.

@-moz-document url-prefix("about:logins"){

button.menuitem-import, button.menuitem-export {
 display:block!important;
}

}

It is not that difficult to create userContent.css if you have never used it.

The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder. • https://support.mozilla.org/en-US/kb/use-troubleshooting-information-page-fix-firefox

You can find this button under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in this folder (name is all lowercase). In the chrome folder you need to create a plain text file with the name userContent.css (name is case sensitive). In this userContent.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userContent.css file as a plain text file.

You need to close (Quit/Exit) and restart Firefox when you create or modify the userContent.css file.

Please see attached image of my userContent.css file within the chrome folder.

I'm certain you will be able to help. Thank you for your assistance.

WED 21FEB24 The urgent issue is that in the last few weeks, many web pages do not load content, just a grey or white screen. Some will load the header. I am the Executor for someone's estate, and I am having this trouble with some financial websites that I must access to do the job.

Its been many years since I upgraded anything. It might be that Macintosh Firefox 78.15.0 esr (64 bit) and Thunderbird 60.9.1 are the newest revs that work with OSX 10.11.6 El Capitan. I have a 2011 MacBookPro.

I don't like the changes in the user interface that Apple put into OSX after El Capitan. But I may be forced to upgrade. Too late in life to learn Linux.

Maybe the minimalist solution is to upgrade Firefox. But that may require upgrading OSX, and Apple has made it really hard to do that unless you go to the very newest. OTOH I don't know if the newer OSX will run on my 2011 MacBook Pro. If I clicked on "software update" in About This Mac, what would happen? would it just start doing it, or tell me about it first?

The last time I upgraded something, probably Thunderbird but maybe it was Firefox, I had to learn a complicated process to copy & save the User Profiles (they are in a hidden directory), and then install them into the new rev. I don't want to go through that again. I just want to run the dmg file.

There used to be a Mozilla web page with all the versions & you could download the dmg file you wanted.

If I still have problems, I would have to buy a much newer computer. A several year old MacBookPro. But I don't like the "new" disk formatting method Apple created. It saves space by not actually making copies of files, but uses a pointer to one copy. So there is a single point of failure, which makes copies pointless. I want to keep using OSX Extended (Journaled) and I would have to have the seller of the computer do that for me, before I used Migration Assistant to put my stuff on it. I also hate the welded-on hard drive; being able to pull the drive is the best "broken hardware" solution.

I don't recall if El Capitan has the "OSX Recovery" system or if that happened in a later rev.

I use SuperDuper to make a clone of my hard drive as a backup & archive. I wonder if I could connect a copy on an external drive and then startup using the external copy. Then I could upgrade Firefox and see if it works, then do the same for OSX if necessary, and Thunderbird.

Suggestions & how-to info needed. TIA

For the past several weeks when I click on Messenger from the Facebook web page I get a blank page with the Facebook header. Same if I click the little shortcut button (brings up a blank box). I've cleared all cookies and cache but no change. I do not have this problem with Safari so I believe it is a Firefox issue and not a Facebook issue.

Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

Dear Firefox Officer,

I have been requested by e-mail to update my Firefox 78.15.Oesr (64 bits) before the end of March. Is this update compatible with my MacBookPro5,4 with IOS El Capitan 10.11.6? Please note that I cannot install a more recent IOS. Without updating my present Firefox, would I still have access to all my favorite folders and applications? Thanks for your help. Best regards, Marcel Arnould

I always thought Firefox Sync was kind of a backup service. Today I was disappointed to learn that Firefox Sync cannot be trusted as a backup service.

A search for “firefox sync” finds 2,929 results in Community Discussion Only.

As late as 2/2/23, Top 10 Contributor Paul says: https://support.mozilla.org/en-US/questions/1404105#answer-1563509

“It appears from your question, that you are using Firefox Sync as a back up service. This is not what Sync is designed to do. The Firefox Sync service takes a copy of the data you wish to include and transfers it to a second device... The storage in between all attached devices is both temporary and fragile and is not stable enough to be (and is not designed as) a reliable backup service.”

I looked through all the Mozilla Help Articles I could find about Firefox Sync. Not one of them mentions that Firefox Sync should not be relied upon as a backup service.

Then I found this blog searching Google: “The Future of Sync”. https://blog.mozilla.org/services/2020/09/15/the-future-of-sync/

In the blog, JR Conlin says, among other things: “A New Hope Service: A lot of folks expected it to be a Backup service. The good news is, now it is a backup service. Sync is more reliable now.”

JR Conlin posted the above blog in Sept 2020. Is there anyone who can comment on JR Conlin’s statement or the progress of his and his team’s work?

Thank You to all volunteers.

Hi, I cannot use wordpress.com. When I click on "log in" it hangs at the redirect and I only get a blank screen.

(Hangs here:) https://wordpress.com/log-in?redirect_to=https%3A%2F%2Fwordpress.com%2F

I've disabled all extensions, cleared cookies and restarted, nothing seems to work. Any help would be much appreciated.

Thanks!

I am running 78.15.0esr on my macbook pro and when I go to Password manager and pull down the menu under the 3 dots I do not have the option of EXPORT LOGINS... (SEE ATTACHED IMAGE) How can I export my login for 1Password since I do not have the option to do so. I can see my passwords and individually see my passwords but cannot export. Since I have 588 passwords I need to be able to create a cvs file.

I am unable to sign up for a credit card. The application form does not come up. There is the possibility that it is being blocked, perhaps by a cookie, perhaps by a security feature in the Browser. How do I turn off whatever is blocking the form from popping up?

I am using 78.15.0 esr Firefox browser on early 2008 iMac with OS X 10.11.6. I can't realistically update the OS, as all advice seems to be that anything above 10.11.6 does not work well with the 2008 iMac. 78.15.0 esr Firefox browser is fantastic and I have been happily using it for a few years now. Why force me to stop? Why force me to stop using my super 27" screen iMac, which still works superbly well and would cost many thousands to replace with a new model?

Hello, For me, there is no substitute for browsing with Firefox. But for some time now I've been getting notices that I'm not using the current browser version, for example in my email program and the banking application. However, Firefox info in the menu says that I am using the current version and there are no updates available. Here is the Firefox version shown to me: 78.15.0esr (64-bit) I work with an iMac of the following version: iMac (21.5 inch, from 2010) - OS X El Capitan version 10.11.6 (15G22010); - Processor: 3.06GHz Intel Core i3; - Memory: 4GB 1333MHz DDR3; - Graphics card: ATI Radeon HD 4670 256MB Maybe my computer is too old for the latest version, but why does Firefox Info show me that the browser is up to date and there are no updates? Thank you very much for a tip Uwe

The top informational header for my Earthlink email has vanished on Firefox. I still receive email but cannot reply/forward via Firefox. a complete and correct Earthlink email is still found on internet and their website.

How do I get the header for my email back on Firefox?

Thank you.

I AM IRATE. I AM SIMPLY TRYING TO DELETE BOOKMARK, BOOKMARK FOLDERS AND THE "OTHER BOOKMARKS" FOLDER FROM FIREFOX AND THEY WILL NOT DELETE. HOW CAN SOMETHING SO SIMPLE BE THIS MUCH TROUBLE. THIS SHOULD BE SIMPLE. I AM USING A MAC PRO.
