Firefox Support Forum

I just updated Firefox to latest version and cannot run it on my current OS. How can I get back to the older version I was using until I'm able to upgrade my OS? As it stands I cannot access Firefox on my Mac. The icon has a big do not enter cross on it. Please help. Fast. Thanks.

When I try to log on to hmnow.com, all I get is a white screen. I worked with Hallmark support, but they couldn't figure it out even though I have a paid subscription with them. I've rebooted my Mac and it says I have the latest Firefox version installed. This has gone on for weeks. I've had no problem with any other website.

Hi. In the past week, my Firefox has been giving me this message for many sites - all of which I've landed on before and I trust. Firefox wants me to contact the website owner which is not do-able. Any suggestions? Thx!

Here's the error msg I get: An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

I did a refresh yesterday and lost my passwords. I have another computer where the passwords are functioning and I have the "old file" but I don't know how to use it. I clicked on the old file, but just came up with another file called EP7i0nok. It doesn't do anything but it just opens up and it doesn't have anything to restore data.

I need a link to download the last version of Firefox that worked with my iOs 10.11111111... version for my OLD MacBook Pro. (2009)... Can't afford new Mac and newest version of iOs won't run on this MacBook... Too old... Same story: need new, no $$$... So, I what I need is a link to the old version of Firefox that I CAN run on my MacBook... One that works with iOs 10.11116 or whatever...

Thanks, humans smarter than me...,

I'm not sure that I picked the best topic, but here goes . . .

Sadly, I used an app called CleanMyMac X and now all of my passwords, etc, that were saved in "Blur" are gone. It seems that Blur might be in a folder called "Old Firefox Data" that is now on my computer's desktop, but all of what might be Blur's data is encrypted and I don't know how to access it.

I have written to Blur, and CleanMyMac, Mail.com, Google, and others, but I only get automated answers that won't work because I can't login to anything because my passwords are not available to me.

What to do? I can't even login to FF, nor can I get the email that FF has for me.

Can I ask for answers at [removed email from public] ?

I have an older MacBook Pro with iOs 10.111111... I tried to update myFirefox browser and found out after the fact that it's not supported by the version I have. I cannot Update the iOs without buying a new McBook... Sadly, no $. Can you assist me in procuring a Firefox version or a link to one compatible with iOs 10.11111...??? I love my Mac but I can't stand Safari...

Thanks ever so much...

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.

Dear Crewmembers,

My query is how can I improve Firefox site performance with an OS X El Capitan 10.11.6 version? To my knowledge there is no upgrade available to Sierra. Are there any possible solutions to the limitations I am currently in?

Kind regards, Fiona

On many, many, websites when logging in I am getting the above message.

These sites work no issues but why is Firefox not recognized as a accepted browser.

Firefox says I am using the current release, and is up to date?

All this sites are important log on, like BofA, OptumRx, etc.

I am using an iMac, Mac OS 10.11.6.

It is still a really good machine.

Comments???

My bank is telling me that my browser is not secure. I check my account daily and this is the first time I have received this notification. What must I do to renew security?

In Amazon.co.uk, when I tried to remove items for view option, the option is not working. I tried with Safari and it works?? so is it a bug with firefox or amazon, but then again why aill it work with other browser....

On start-up the Firefox browser shows a list of articles/topics that is referred to as Pockets. I clicked on one from Orion Magazine this morning and after the article was up for about 30 seconds a graphic appeared that showed a large metal looking sphere and was suppose to augment the article. This graphic completely locked up my computer. I am running an ancient iMac, mid-2007, and it took bringing down my wi-fi network and a little frustration to get my computer unfrozen. Please take down this article.

Using Firefox I can no longer search for Yelp support.

Hi

I accidently unistalled firefox on my macbook pro, I had to re install. I had to sign back inot fire fox by creating a new account under robinpegden@icloud,com.

I already had a firefox under this user name. Can you link my old account so I can transfer all book marks saved etc? thank you.

My email address is above

I need to access an essential security device that has an address similar to my modem, with numbers and periods only. But Firefox consistently adds either "HTTP" or "HTTPS" to the address, so Firefox says, “Unable to connect.” I am able to access my modem page without Firefox adding anything to the address. The instructions I found (at Support.mozilla.org/en-US/kb/https-only-prefs) say to disable or insert exceptions in the “HTTPS only" option on the “Privacy and Security” section of Firefox Preferences. However, there is NO "HTTPS only" selection in my Preferences (Version 78.150esr). The other suggestion, to “Click the Lock icon in the address bar,” will not work because there is no Lock icon in the address bar with this address. I have "Use the address bar for search. . ." unchecked in the "Search" section of Firefox Preferences. I also tried unchecking “Provide search suggestions,” disabling all of my Firefox extensions, and using “non-private browsing” mode. Safari browser will not connect to this URL either. Help!
