Firefox 社群討論區

As the question stated I have navigated to my mozilla profile folder, ( C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\pw1dnvcy.default-release ) but there is no file called persdict.dat. I have ensured all file name extensions are visible, & none are hidden in windows file explorer (Win 10). I am at al loss I cannot figure this out.

Updated recently from (I believe) 138.04 to 139.0.1, and immediately noticed that the size of font (and icons) had changed in the folders I have in the bookmark toolbar, that is they are much smaller and thus also less space between. Why this, and is it possible to change the size, without changing something else?

It's possible that many don't have folders in the toolbar and thus don't notice, but I have 2-3 apart from bookmarks.

I remember a change many versions ago that increased the space between entries in the bookmark menu, and also in the bookmark toolbar folders. That was too much and I found a setting [in config] that could be changed to decrease the space back then. (I haven't looked for that solution now, probably have some doc somewhere, and won't bother searching since this is different. Same with this case; I did some quick initial search but found next to nothing and older. BTW, this is one of the downsides of changes like these and similar; the day you have too move to another OS version, i.e. reinstall everything you also have to keep documentation of all these little changes, apart from all the other things you'll have to export or save.)

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

I have the box ticked in Settings for previous tabs to be installed on Startup but it isn't happening although it used to. I was trying to get rid of caches (what are they?) and must have done something.

The recommended methods, changing to this in the registry :

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\Certificates] "ImportEnterpriseRoots"=dword:00000000

Reverts back to 00000001

Put this policies.json and did nothing: {

 "policies": {
   "Certificates": {
     "ImportEnterpriseRoots": false
   }
 }

} What am I missing or what's changed?

My specific need at the moment is to add another search engine option in about:preferences#search

Thanks.

When I launch the browser, can I not preload tabs that I have not used yet in this session, but which are open from the previous one? This is slowing down my weak PC. I did not find anything about this either on the Internet or in the reference book. Thanks in advance for your answer

I tried to add the roboform browser extension twice and I get the following message (the second time was from the Roboform homepage):

Installation aborted because the add-on appears to be corrupt. Preview of RoboForm Password Manager RoboForm Password Manager by Siber Systems Recommended

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

Back around February (2025), the full screen mode by pressing F11 quit working. Clicking the diagonal two pointed arrow in the application menu didn't do it anymore either. Both actions only toggle the bookmark bar. I've tried reinstalling, and waiting for further updates. So far, still no luck. I've since moved on to using another browser, since I often want this feature. Does anyone have the same problem or know how to fix this?
