Firefox Support Forum

My present iMac is failing rapidly and I will be replacing it with a new Mac very. I do not have a Time Machine backup. The only info I really need is how to copy off, to an external drive, all the bookmarks and bookmark structure), extensions, and add-ons I have added to Firefox, and then add them to Firefox on my future Mac.

Do I just copy the Firefox app to the external drive? I looked in the Macs' base system Library and Preferences, and in my User files, but I do not see anything related to Firefox.

My old (current) and failing Mac is running the latest version of Catalina,

Thanks for any info!

A few days ago my electronic certificates have disappeared from the firefox container The certificate provider has vetoed me from delivering a new certificate, because it is the second time Firefox has lost a certificate in 2020. The certificates I need for any management before the administration of Spain and more now with the COVID After it is granted, you have to verify your identity with the Tax Agency, and they have already called my attention for renewing the same year a certificate that firefox loses when it is updated. I'm very, very pissed off I will have to switch to Chrome

Hi,

I am using FF for my automation testing.I run lot of FF instances/windows in parallel. For example if I run 20 window in HTMLUNIT-Driver then my cpu usage is only 5 to 10% but if i run 20 FF headless then my cpu usage is 80=90% .

I tried FF 80 . Still same behaviour

Stackoverflow question : https://stackoverflow.com/questions/57935905/selenium-firefox-69-high-cpu-usage-java?noredirect=1#comment102532709_57935905

question :

Do we have slim version of headless FF which will use less cpu like htmlunit driver . If not how do i optimize FF so that it uses less cpu like htmlunitDriver

The updated version 82.0 automatically installed on 10/21/20. Now, when I'm browsing and click on a link, the window does NOT open in a new tab. I've checked setting/options and "open windows in new tab" is checked. Did not have this issue prior to the update. Help.

hi All, I had a disk crash and had to reinstall Win10, which cleverly backs up everthing in a .OLD file.

Back in the midst of time I did something 'clever' (Read: stupid) and by the looks of things (directory size) I kept my FF profile in MyDocuments (why???). Anyway, importing that profile has lost my passwords!!!

I have my bookmarks but they've been imported into a 'higher' directory and I need to view them through the popup box as they're not visible on the toolbar. I also have all my history and download history.

I'm a good boy and have a different password for every site and a variety of email addresses, so needless to say, it's going to be a pain to reset everything. I also imported the profiles from appdata\..\profiles but nothing of any use was there.

please help.

TIA Adrian

Hi, Firefox desktop for win 10: Firefox works with this one exception... I downloaded two "self extracting" files from Nikon. When I double click on either or any file of this type using firefox, I get "some installation files are corrupt, please re-download" If I use Microsoft edge, the same files work, provided I select "unblock" in the files properties tab. (yes I do this for ff files too)

This did not happen months ago and I'm sure this is because Microsfot has changed something, which needs all browsers to adapt to. Thx

This is a pretty weird problem. When I go to download a PDF from our company's website, Firefox is asking if I want to open it or download it, and here is what happens with both options:

• Open -- It identifies the document as HTML and presents the raw PDF data (it becomes file.pdf.html)
• Download -- It downloads the file correctly as a pdf, and calls it file.pdf. The file can then be opened and correctly rendered as a PDF.

I'm assuming it is an issue with the response header-- either it is malformed or non-standard, or maybe it is just Firefox being wonky. IE, Edge, and Chrome have no problem with it.

The mime type is application/pdf, and we are using a Content-disposition: attachment; filename="file.pdf".

Hopefully this is an easy issue to fix, but this is out of my normal realm of programming. The Firefox users where I work know to download the offending files instead of immediately opening them, it would just be nice to actually fix the issue.

Oh, in case it helps, part of the HTTP response header that we are sending is telling the browser to treat the file like an attachment, so the other browsers just save it.

Thanks for any insight and help!

I clicked on the update button last night - running 81.0, and the update was for 81.0.2. When I went to open the browser all that I got was a line at the top - FF would not open. I backed up the profile, and did a clean install. When I finally got the backed up profile installed, it opened properly once and everything was there. When I opened it again, no book marks, and none of the buttons worked. FF didn't close properly, and I had to use Task Manager to shut down.

I ended up downloading the beta version, and it's worked just fine. The original profile works, so all bookmarks are there.

I see that FF released 82.0 this morning. Is it safe to try to install it, or is the beta version that I installed last night really 82, just hours before it was officially released?

A form I need to use requires that javascript be enabled. Yes, it's a US government form. I use Firefox 81.0.2 I will likely need to have step-by-step directions. Thanks.

One of Opera's best features (for me) is Speed Dial , which is roughly similar to Top Sites ... I use it a lot - how do I import Speed Dial entries into Top Site? Thanks

Like I said, upgraded to Windows 10 over the weekend. Figured there would be some tweaks and hiccups, but this is getting out frustrating. We use Google Drive for work, often needing to download files from there. Upon attempting to download anything I'm redirected to a page with this error message:

"The page isn’t redirecting properly

An error occurred during a connection to doc-0o-6k-docs.googleusercontent.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies."

I've reinstalled, checked for updates, snagged java, flash, tried firefox safe mode, cleared cache and cookies, and I'm running out of ideas here. Seems to be no problem using Chrome, so problem is unique to firefox which is unfortunate since FF is my browser of choice.

Cheers for the help in advance!

On installing Firefox today, I tried importing my passwords from Chrome. It seemed to work with no error report but, when I accessed any sites, the saved passwords that Firefox auto-filled were all incorrect. I'm not going to reset scores of passwords. Is there something I should do, apart from uninstalling Firefox and reverting to Chrome?
