Firefox Support Forum

dear ladies and gentlemen,

Firefox has been delivered with the new print dialog since version 82.

I have to print around a hundred PDF files at work (usually only the first page of the document). The new print dialog means that there is a lot more work for me here.

Is it possible to set the "old" system print dialog by default or to instruct firefox to always print only the first page of the document by default?

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).

i am trying to download a file (about 50gb) and the download keeps failing. When i click reply the download continuous. It downloads fine for a little bit then it fails again. Keep in mind when i click the trry agin button the download does not restart, it just continuous to download where it left off. (sort of like just pause and unpause) what should i do?

Good afternoon folks I can't watch Netflix on my Firefox browser. Do you know why is there a plug-in what is missing or something? He says the version is not up to date While my Firefox is always up to date, can you help me further. Thanks in advance from Trimmy.

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

As you all might know, TLS 1.0 and TLS 1.1 have reached their End Of Life, and are no longer supported. I have looked inside the latest firefox (77.0.1 (64-bit)) configuration, and found the following configuration set by default (included in the first image).

I attached a picture of my firefox about page, hope to receive an answer soon.

Thank you, Guy

Hi,

I brought my computer to Best Buy for some audio issues it was having. They reset my OS and drivers and now I lost all of my Mozilla Firefox bookmarks and passwords. I do not have a recent JSON backup file. How can I recover these?

Thanks.

HERE IS THE ANSWER Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it. You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right --menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/

Also to make the tabs wider or narrower, modify the line which is coded width: 50vw !important;

Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit. When all the toolkit options appear change the one which says toolkit.legacyUserProfileCustomizations.stylesheets to TRUE by click the icon in the right hand column. Than close Firefox and reopen, and check how it looks This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.

Some of well known sites such as "drive.google.com" & "mail.yahoo.com" is resulting in "Did Not Connect: Potential Security Issue page" in Firefox. They are opening just fine in other browsers.

This issue has cropped up since past week in Firefox. Not sure what is the root cause behind the problem. I have tried re-installing Firefox, but still no change.

I have checked the certificates of those sites, and they are seems to be in order. I mean other browsers are able to open without issue, then why Firefox is not opening them for me?

Please let me know if this issue can be fixed in Firefox.

How can I change the DNS Server in FireFox to whatever DNS I want and not what Mozilla wants?

For example: Google DNS 8.8.8.8, 8.8.4.4 or, Open DNS 208.67.222.222 · 208.67.220.220

Enabling DNS over HTTPS dose not give me FULL control over this. I should be able to put a DNS IP address in there like in Internet Explore.

All of a sudden, my bookmarks ( and other bookmarks) are double spaced. This just happened today and I didn't make any changes. How do I get rid of the double spacing ? Thank you.

My system requires me to log in to the internet when I start up. Usually I am given a message and asked to click on a link, which brings up my login page. Since yesterday I have been receiving the following message: 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." I have cleared my cookies and cache and restarted numerous times. This message keeps coming up. I am able to access my home page, but any attempt to click on bookmarked links results in this message, and occasionally it will refuse even that, telling me it's redirected me too many times. Apart from clearing my cookies cache, which doesn't help, what else can I do to fix this problem? Thanks

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

I just deleted my cache / history, and for some reason this also took Foxit Reader out of my printer options. How do I get it back in? I Tried using "Find Printer", but it would not except an .exe as a printer. I first put Foxit in so long ago, I have no memory of how I did it. I print to pdf most of the time when saving a receipt, etc. and would rather use Foxit than ms. Thanks

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

This page keeps refreshing itself. Clicking the Refresh X stops it:

https://www.healthline.com/nutrition/decaf-coffee-good-or-bad

. . . since I just updated to 78.0.1 (64-bit) . . . ? It looks like a bug to me.

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

• This happens for any filetype, from any source.
• It started happening about a month ago.
• Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
• If it's a small file and I try repeatedly, it sometimes will eventually download.
• Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
• I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

• Used Refresh Firefox
• Cleared download history
• Changed download location
• Reset browser.download values
• Disabled firewalls and antivirus/spyware
• Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
• Cleared cookies and cache
• Ran in safe mode
• Verified Temp folder filepath was valid
• Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
• Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

• I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
• Verified places.sqlite was not set to read-only
• Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!
