Hi Ariaena, Here you can see how to set the bookmarks folder or its destination or put into some other folder see here from this link https://support.mozilla.org/en-US/kb/bookmark-folders-organize-your-bookmarks?esab=a&s=bookmarks&r=6&as=s#w_putting-bookmarks-into-folders

That is completely unrelated to my problem.

Try change the resolution of your monitor or the resolution of firefox

To change the resolution firefox hold Ctrl e press - (minus) To change the resolution of your monitor go to COntrol Painel, Video, at the Settings tab, increase the resolution

Changing Firefox's resolution didn't work. Didn't affect the size of the Properties box at all. I'd rather not tamper with the resolution of the monitor, because it took me ages to undo the mess Firefox created after the bull update that forced my browser to resize itself according to my monitor resolution.

It was a stupid, stupid update. But I edited the layout in about:config.

Mayhaps that is the problem?

You can check for problems caused by a corrupted localstore.rdf file.

• http://kb.mozillazine.org/Corrupt_localstore.rdf

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

I'm not sure what the problem is, but upon restarting Firefox in safe mode, the Bookmark Properties box is considerably smaller, taking up the approximate space of half of this post box.

Does it stay that way when you start Firefox in normal mode or does the problem return?

The problem returns when Firefox returns to normal. The box is stretched far across the screen like in the screenshot.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled and the default theme then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

I disabled each and every one of my Extensions in normal mode, yet the problem persists. Very odd. I only have the default Appearance, so that can't be the problem.

Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

I disabled it, but still no changes.

I'm not sure from reading the various back and forth whether you tried renaming the localstore.rdf file?

Open your current Firefox settings (AKA Firefox profile) folder using

Help > Troubleshooting Information > "Show Folder" button

Leaving that window open, switch back to Firefox and Exit

Pause while Firefox finishes its cleanup, then rename localstore.rdf to something like localstore.old

Restart Firefox. Your toolbars and window and dialog dimensions should revert to factory defaults. Does that make any difference?

Yes. "Fixed", in a way. The Bookmark Properties box now resembles that of Safe Mode's, which is a bit too small for comfort. Still, I guess you can't have everything.

I now have a new problem however. The Bookmarks toolbar functions perfectly well. However, my Bookmarks menu is now broken. When I right click on anything in the Bookmarks menu - be it a folder or a link - all options are greyed out except for "Open all in tabs".

I can't create a new folder or copy or paste or view properties of anything in the Bookmarks menu. All greyed out.

Edit - Never mind, restarting Firefox did the trick. Case closed, thank you all for your aid.

Hi Ariaena, there may be a way to widen the Bookmark Properties box using a custom style rule. If you think it would be really helpful, I can try to research that tonight.

Oh no, that's quite fine. I actually found a way to get over that. Right clicking and press "Size" then resizing using the arrow keys on the keyboard did the trick.

Which leads me to wonder if this option was open during the Bookmarks-Properties-Too-Long period, because it would've saved a lot of trouble.

Hi Ariaena, that's genius, using the window control menu for resizing a dialog when the mouse method isn't available. It probably would have worked before, too. I think the trick to reducing width in that case is to press the right arrow key once to select the side you are moving, then use the left menu key to move it leftwards.

I never did understand how to use the Size feature until I googled it to find out. Now I can resize it to my heart's content (ﾉ´ヮ´)ﾉ*:･ﾟ✧
