Firefox Support Forum

All three boxes under Options, Privacy, History, Firefox wil: Use custom settings for history are checked. I need to know what boxes are checked (if any) as default. I will not select Use default to find this out because I do not want my other settings to change to default. Can anyone tell me what the default setting is for this option? Thanks in advance.

This question is a follow-up to support.mozilla.org/en-US/questions/1243718. When I turned off anti-aliasing, text became much more readable, but still not as good as it was in FireFox 22 (see attached picture for comparison). Any ideas? (I would be more than happy to continue using FireFox 22, but there are a lot of Web sites that require encryption algorithms that FireFox 22 doesn't have, so I am compelled to use FireFox 52 with all its problems, tabs that take up valuable screen space and are impossible to turn off, and unreadable ClearType text with smudged letters that make me nauseous. I think whoever coined the term "CLEARType" was a very sick person).

I'm trying to upgrade from V52 ESR - kept for known and obvious reasons concerning addons compatibility - to a current V81. Copied the profile data from user/appdata/mozilla/firefox.../myprofile/*.* - including "key3.db" (in use), "key4.db" (don't know where this one originates from - shouldn't exist at all for versions < 57 or so) and "logins.json".

So far stumbled upon:

• No Logins in new system visible. No master password set. After setting a new master password, still no logins visible.
• This very forum here suggests - in many threads for version upgrades from somewhere in the 50s to up to the 70s - to simply copy the "key3.db" and "logins.json" and to delete the "key4.db" on the new system's profile. That does not change anything at all.

Am i forced to keep the V52, now not only by means of addons compatibility, but also by means of login manager compatibility?

What would the correct path to upgrade be? Would i have to install each and every in-between-version from 52 to 81 to be able to migrate? Will i run into the exact same trouble doing it that way, only burning daytime for nothing? Or is it guarantied to somehow get the logins data transfered to the current version? How did all the Millions of other users fare with that aspect? Is that an extremely rare case where users set a master password, so that developers decided to not care anymore about those nasty paranoids?

Hello! I`m have trouble to install mozilla firefox 54 on my PC on Windows XP. My main PC died and I have no money to buy new or fix my but I need to study. Please help!

Am using the ESR channel for Firefox (32-bit), and am at the latest version 52.9.0 My Panasonic Toughbook CF-29 is running WIndowXP SP3 Two issues: (1) Am running into problems with one or two sites who appear to be lax about initializing their variables. The workaround is to reload a page once or twice. Or, in the case of input being required, to enter incorrect data the first time. My assumption is that new browsers are more "forgiving". (2) Flash is being discontinued. Will Firefox 52.9.0 (32 bit) be able to cope with what I assume is the move too HTML 5 Happy to help in anyway with either or both issues.

When I click on my spam folder there always was a selection that said something to the effect "Block future emails" and in the last two days this does not show up when I want to premantently block spam sent to me - makes no sense that this selection is just gone

I have always had this set, but suddenly links have started opening in a new window [another Firefox browser opens], and despite checking open in new tab is set, it continues.

There is no true reason for which I am using an ESR version I could use another but in this moment I have to remain on XP on this PC. So is there a Firefox version that can display the HTML 5 video on a WIN XP PRO SP3?

I use cryptographic module PKCS#11 to browse some sites. I load corresponding xxx.dll file : Options>advanced>Certificates>SecurityDevices>Load . The PKCS#11 device appears in the Device Manager list of devices. I can Log in this PKCS#11 reader and view data. "OK", View Certificates - I view this certificate. "OK" and quit Options menu. If I close the FF browser, these settings was lost and I have to install them manually again. How to save these settings ?

My computer is to old to upgrade. I am running firefox 52.9. Most of the time I keep getting not responding errors. I have to shut down firefox and restart computer. Sometime this works and sometimes it doesn't help.

Way way back (like version 17 or so), it was easy to set Firefox so that PDFs opened --

   -- in Adobe Acrobat, in the tab

I had version 50 or so set up this way, and then accidentally "updated" and had to reinstall from scratch.

I have done

    Options > Applications > PDF > open in Adobe Acrobat

That gets me less than I want -- when I open a PDF, I get --

    open a new tab
    download the PDF through "save as" dialog box, and
    leave the new tab white

What I want is what I used to get in the early 2000s --

   -- the PDF open, in the tab, in Adobe Acrobat
   -- with the URL of the PDF in the address bar

Thank you
