What is the last Firefox version that works with MAC Lion OS X 10.7.5?

I have a study program of that vintage that plugs into firefox and the version on the computer now is 3.0.10 (from year 2009 and the program does not work with it.

The program is compatible with Lion OS X 10.7.5 but the Firefox version is too old.

The version 3.0.10 on the computer does not work well with most sites or crashes. The intent is not to expect to browse, just be new enough for this program for its dedicated use.

The proton changes might make for a better smartphone experience, but it really trashes operations on computers. In case you are wondering why firefox's share of the browser market continues to slide, upgrades like "proton" are the main reason.

I found the following css for highlighting all context menu items for Firefox 91 ESR (not working on side-bar items from hamburger menu) /*************************** Highlight context menu items

• • • • • • • • • • • • • • • • • • • • • • • • • • • /

menu[_moz-menuactive="true"], menuitem[_moz-menuactive="true"] {

 background-color: #e8eefd !important;  /* blue 95% lighter */
 color: #3d3dff !important; /* blue 62% darker */
 /* https://www.w3schools.com/colors/colors_picker.asp */

}

How do I apply the same highlighting shown by the red arrow to the text where grey and heavy blue is used for highlighting? I find css very convoluted and it's hard for me to know what ids/parameters to use to get the desired effects.

I get backup from my filrefox such as :

cp -rv ~/.mozilla/firefox/* /mnt/my_external_hdd_mounted/myfirefox/

In new linux I did the following steps:

1. rm -rf .mozilla/firefox/* 2. cp -rv /mnt/my_external_hdd_mounted/myfirefox/* ~/.mozilla/firefox/ 3. chown mohsen.mohsen -R ~/.mozilla/firefox/

By the way, both of them are version 91.

But after run of firefox, I get the error of attached picture.

How can i customize Firefox with my own privacy-settings and save those settings for a new installation? Each time after installing Firefox i must go trough all the settings once again. To avoid this time consuming steps, is there a way to import all user-specific-settings for a new installation? The screenshot i attached below clearly shows IT IS POSSIBLE to pre-edit firefox settings for a new installation. Question remains, how can i do that?

For example i wish to always use those settings: (all set to false)

toolkit.telemetry.enabled privacy.resistFingerprinting geo.enable extensions.pocket.enabled media.peerconnection.enabled browser.urlbar.placeholderName > DuckDuckGo

-nevery remember history -dns over https -block tracking content in all windows (not only private) -block cross site and social media tracking -ublock origin extension active -delete cookies and site data when firefox is closed -enable https only mode in all windows

Under: about:config browser.taskbar.lists.recent.enabled false

I have just made a Windows 10 system and I am not understanding the features now existing that weren't with Firefox on my Win7. I have turned the 'Frequent' off and now right clicking the Firefox icon produces 10 'Recent' listings. Being that I've changed FF's config to false, I do not know how to make these 10 'recent's permanently disappear. Right clicking one of these entities and removing only replaces with another.

Please help me to permanently remove 'Recent' from my right click of the Firefox icon in my taskbar.

The following I wrote to initially question why showing dom properties didn't work at all, but I only had tried it on an textarea example on developer.mozilla.org so far. Turns out, on right this support forum's textarea I'm right now writing in, it does work. Could I make it work on developer.mozilla.org, too, like it works here on support.mozilla.org? That would be useful to inspect the html and javascript examples on there.

Original planned question: I very recently updated to Firefox 91.3.0esr (64-Bit), and I restarted working with the developer tools.

As far as I can recall it was possible to see an overview of an html page's element's functions somewhere in the developer tools. I tried "Untersuchen (Q)" ("Examine" or is it "Inspect" in English) on the textarea (in https://developer.mozilla.org/en-US/docs/Web/API/HTMLTextAreaElement ). This openend the developer tools panel, the html was shown and the textarea-elemtent highlighted. There I right clicked and selected "Dom-Eigenschaften anzeigen" (View dom properties). The console opened, and showed: inspect($0, true) Restricted { }

(I want to access all the scroll properties of the textarea, and possible functions to scroll the textarea using javascript.)

Under the settings page of the developer tools -> standard developer tools -> I actived the checkbox "DOM", and restarted the browser (using the restart option under about:profiles).

There is a known issue for some i3 users that when we click the right-mouse button, the context menu will pop up in a position where the first item in the menu is already highlighted, so when the right mouse button is released, it automatically "selects" that item. So if we want to copy a link, for example, we have to be careful to move the mouse before releasing the button or that link will immediately be opened in a new tab.

What some of us have done in the past is to create a userChrome.css file setting a top (and/or left) margin for that menu, which fixes the issue.

In the latest version(s?) of Firefox, this no longer works (but other userChrome.css rules I have set up continue to work), so I'm assuming that the ID of the context menus has been changed. What is the ID now?

For example when i download Tor they share a PGP KEY to verify the integrity of the downloaded exe. Other websites share for exmaple sha 1 or sha256 or md5.

However i cannot find any such option for firefox browser. Am i blind or it doesn't exist? Then how am i supposed to be 100% sure that my downloaded exe has not been modified by someone like my ISP, Government, Criminals/Hackers?

I was wondering why there's so many processes of Firefox that are displayed as running in Task Manager.

Initially it was about 7-8 and even that was something that drew my attention and concern to it but now there's 22. It's very frustrating and any feedback towards resolving this issue would be very much appreciated. Thank you very much, you're beautiful.

Firefox currently has a URL color formatting scheme which greys-out all parts of the URL in the address bar except for the top-level domain and the 2nd-level domain (with some exceptions).

I am building a website where my organization-specific domain is NOT located on the 2nd-level domain, but rather on the 3rd-level domain.

I plan to use the domain "obb.ll.land". The "ll.land" part is basically a domain that the Liberland Government operates and from which it sells 3rd-level domains to members of the public. Think of "ll.land" as a temporary ccTLD for Liberland. (ICANN requires countries to be on the ISO-3166 list—which Liberland is not yet on—in order to register an official Internet ccTLD.) Therefore, any domain that is formatted as "[SUBDOMAIN].ll.land" should be presumed to be the foundational domain for a given organization that uses it.

Therefore, when a client sees a Liberlandic website, the domain should have the 3rd-level domain included in the black-text portion of Firefox's URL color formatting scheme. Otherwise the scheme would be misleading about the true nature of the website involved. For example, the 3rd-level domain of "https://www.floating.ll.land/" should be included in the black-text portion. Same with the 3rd-level domain of "https://register.ll.land/". However, as of this writing, no ".ll.land" site has the appropriate URL coloration to my knowledge.

How can I solve this problem? Is there something which developers like me should add to our websites individually, or will Mozilla be responsible for handling this matter?

Thank you all in advance! :)

Hi,

I got an issue that bookmarks are saved in the library, but this doesn't reflect on the Bookmark toolbar.

I have already removed the entire profile, did a reinstall .. nothing seems to reset it. When I perform a backup, the entries are also in the backup json.

I hope somebody can help, this started happening recently it seems.

Thanks in advance!

How can i stop firefox from going there and stick to the original URL?

And if this cant be prevented, could you give me an idea how i could still access the first URL?

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

Hello, I signed in to Firefox on a new computer and it appears to have synced to the new computer, overwriting and erasing all my bookmarks. I use Firefox at work because I need to move through several computers. Firefox allows me to bring my bookmarks with me to each station. Now it appears I may have erased all my bookmarks by syncing this new computer, not the other way around as it always has. Please help me recover my bookmarks.
