I am using Thunderbird 91.0b3 (64-bit) on Linux Mint 20.1 running XFCE 4.14.3

I am trying to set TB to open a PDF attachment in the external system viewer Xreader.

I have tried the following:-

1) edited the mimeTypes.rdf file with the correct lines for a PDF (https://termbin.com/qwpf).

2) deleted the mimeTypes.rdf file and tried to set it in Preferences.

3) edited user.js

In Firefox there is a well documented way (https://support.mozilla.org/en-US/kb/view-pdf-files-firefox) to set this up but I could not find the same for Thunderbird... why not?

Which magic file is it??

Is it mimeTypes.rdf or user.js or handlers.json ?!

Hope anyone can help.

Ever since yesterday when I accidentally turned on caret browsing I've been trying to turn it back off. I've been pressing F7 in an attempt to bring up the pop-up, but to no avail. I've been searching all over the internet for solutions, but nothing has helped yet. I'm only able to find articles on disabling caret browsing in Microsoft Edge or Google Chrome. Obviously, that doesn't help me with Firefox.

I am on MacOS Mojave (10.14.6). I have a few different installations of Firefox for different purposes and I'd like them each to display the custom name I've given them by renaming their filename (e.g. changing Firefox.app to something like YouTubeViewer.app). This causes the installation of Firefox to show in my app switcher and elsewhere in the OS as "YouTubeViewer", however when I run YouTubeViewer.app, Firefox still displays "Firefox" in the upper left-hand corner as the application name.

I tried editing the .plist file for each installation to change the value for key CFBundleName from "Firefox" to "YouTubeViewer", but that causes that installation of Firefox to no longer run. I believe this is due to the code-signing and pre-run validation done by the OS.

So, is there any way to get the custom name to display or is just not possible?

I'm running TB 78.12.0 and trying to follow this solution: For Windows, open Tools/Options/Advanced/General/Config. editor, or click the 3-bar icon at the upper right, Options/Options/Advanced/General/Config. editor, right-click the preference layout.css.devPixelsPerPx, Modify, and enter a value of 1.20 or 1.25 or 1.5 or 2.0...

This may or may not be immediately applicable to TB 78, but I haven't been able to find the indicated places. I'm not at all tech literate. To be usable by me, all answers would have to include express statements that more advanced users can avoid. Where is "Tools/Options/Advanced/General/Config. editor" in TB 78? Where is "Options/Options/Advanced/General/Config. editor" in TB 78?

Thanks in advance for your help.

The print functionality has changed a lot in the latest versions of Firefox and is causing me problems so I wonder if there are settings or add-ons which I've missed which would help.

Specifically:

1) The preview is no longer full screen. This makes it difficult to adjust a view, of say a map, so that the area printed is precisely what is wanted. The full screen preview in older versions of Firefox made this very easy. Is there any way of getting a full screen print preview page?

2) Previously it was possible to set custom headers and footers on a printed page. This was ideal for labelling printouts is a descriptive way, so useful for future reference, and enabled the removal of unwanted information. In the present version of Firefox all I seem to be able to do is switch printing of default headers/footers on and off. Is there a way of customising headers and footers that I've missed?

Thanks

I was able to change the font in Ctrl J by changing my system font (windows 10, Firefox font used to automatically follow it). However after the latest Firefox update, that no longer works for Firefox (my system font is still OK). Please help me change the Libabry font again! The default font (probably SegoeUI) is very hard to read on my computer, it's blurry and comes in light gray.

Note: I'm not talking about the website font (it's fine and can be changed in Firefox settings). The library font size is fine too, only the font itself is too hard to read.

Note2: I tried changing my system font to other random fonts (using the registry), restarting my computer in between etc. That still works, but Firefox won't follow.

Toolbar folders -> drop down orientation problem -> screen limit not recognised

Hello:

Quite a few iterations of Firefox ago (cannot recall which), the orientation of the drop down menu listing the bookmarks inside any folder in the toolbar was either towards the 'left' or towards the 'right', depending of the amount of screen real estate available to the right side of the screen where it was opened.

If the listing could not be properly seen by opening the drop down menu towards the 'right', it would be opened towards the 'left'.

This worked perfectly well with my three screen setup, with Firefox in a window in the centre screen. ie: Firefox knew it was inside a three screen wide setup and in the centre screen, so it also "knew" that the right edge of the centre screen was the limit for available screen real estate.

At some time this stopped working in the described manner.

It seems that Firefox now ignores the right edge of the centre screen and as a result the drop down menu for any folder in the toolbar opens to the 'right' and invades the right screen. (see attached screen capture)

If Firefox is opened in a window inside the right screen, it proeprly recognises the right edge of the screen as the limit and acts accordingly.

This is quite a problem for me: I make intensive use of the toolbar with bookmarks inside folders and subfolders and this heavily affects my everyday work.

Is there a way to get back to how it used to be? ie: Firefox using the right edge of the screen it is opened in as the limit to open a drop down menu.

Thanks in advance,

S.
