Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

So, please help and advice further. Thank you in advance and best regards!

I have updated Firefox from 115.16.1 to Firefox ESR because I use a Mac running OS 10.13.6. Is there a way, hopefully an easy way, to import all of the bookmarks and extensions I was previously using in 115.16.1 to ESR. Hope so. Thanks!

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

Hi,

I seem to be having a really odd issue where each time I restart Firefox, recent addons I've installed will not function or appear in the Add-On drop down menu (despite being meant to appear in such), despite being enabled and still being shown as such when I check settings. They only become visible and functional when I disable and re-enable them.

I've just discovered the same thing seems to happen in reverse too. I recently disabled ClearURLs due to a bug it was causing in Google Drive, yet it appeared in my Add-On drop down menu after restarting. Checking settings showed it to still be 'disabled'.

Things I've tried:

• Restarting both Firefox and PC.
• Uninstalling and reinstalling the effected Add-ons
• Deleting my extension*, compatability.ini and prefs.js files - erasing all my add-on settings yet still not helping. This is the main thing I've suggested on forums like this with similar questions, but has not helped.

It seems to only be effecting the most recent set of add-ons I installed over the last week, as if Firefox keeps trying to work with the Add-on settings I had at a previous date. I've seemingly had some cases where the extensions disable or are uninstalled entirely but I'm not sure this is related, as I think it only happened once.

I suspect it's not to do with the new extensions themselves, given it's effecting all the most recent ones, but I'll list the ones I've seen it effecting here regardless:

ClearURLS (not recently installed, but as mentioned showing similar reverse effects) Undo Close Tab YouTube NonStop Privacy Badger History AutoDelete Don't Accept Image/Webp Decentraleyes Xkit Rewritten Disconnect AI Grammar Checker & Paraphraser - LanguageTool &udm=14

As you can see I recently installed quite a few anti-tracker type extensions which probably overlap in function, mainly just to test them out, so it could be connected to them I guess... but seems unlikely.

Thanks, Matt

I have got a message: "Error: Platform version '130.0.1' is not compatible with minVersion >=130 maxVersion< =130.0" I can´t get any connection. What am I going to do and how can you help me?

Hello,

today I have installed new OS and new Firefox.

Because I was syncing everything I thought after login everything will be same as before.

Before reinstaling OS I didnt export anything from Firefox. Now I have no bookmarks, no history, add-ons.

I do keep Lockwise on my iPhone and it connected somehow with my desktop browser so I have passwords in my browser now (thank god for that - otherwise I have no clue how they got there).

Is there a way I can restore Firefox (bookmarks and add-ons) to how it was yesterday?

I dont have firefox install elsewhere, just on my desktop.

Thanks a lot for help

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

I have just logged on for the day and the Side Bar has changed. It now has an extra layer making it wider which now pushes a highly used website page off the screen which is very annoying because I don't want to reduce it's zoom any more.

I use the Side Bar to bookmark various links within this website as shortcuts to navigate it.

How do I remove this unwanted extra layer?

Please find attached a Snipping Tool file.

The unwanted extra layer is the bar down the left showing my Bookmark icon on the top and the Settings icon on the bottom neither of which I want or need and this is causing the extra width to the sidebar which is upsetting my viewing. How do I remove this new bar?

Hello team, When using Firefox to access an application that calls for Java applets, I receive a message saying "frmserlet-3.jnlp. Application not found." (screenshot attached). This did not happen before October 2024.Please help me with a solution. Thank you!

Firefox auto updated when I opened it today. Then when it opened, all that was on the screen was the menu (file edit view history bookmarks tools help), the "search or enter address" box, and in the upper right hand corner the words "private browsing" with the purple circle and eye eyeglasses icon. That's all. I have tried looking at my profile. It seems to still be there. This seems to be a problem with the Firefox software itself. I have re-downloaded the software three times, the last time I uninstalled Firefox from my laptop and totally reinstalled. Every time I get the same results. This almost blank screen. Let me be clear. There is no purple background, there is no Firefox icon, there are no tabs, there is no customized menu bar, there is no search box in the middle of the screen. I'm working on a Windows 10 laptop 64 bit. Please don't tell me to upgrade the Windows 11, the laptop won't take Windows 11. I get the same window whether I open the regular fire fox or the private browsing Firefox.

I recently read the article about the root certificate expiration and the updates related to it (https://support.mozilla.org/en-US/kb/root-certificate-expiration ). I wanted to understand whether my add-ons will be affected because of this. Types of add-ons which i have 1) Simple searchOverride functionality 2) Simple functionality that communicates with remote APIs to display some data.

After recent update bookmarks disappeared. When I restore them and then close firefox developer edition the bookmarks toolbar is gone again. It seems like a bug in that recent update. Please advise.
