why can't I access my add-ons

Posted

When I click the add-on button Firefox opens on a blank page with my add-on links on the left hand side. It opens selecting 'get add-ons' and all that shows is a box saying 'loading' and the rotating icon. They never load. Going down the links the next is 'extensions' resulting in a blank page and nothing else. Next is appearance where it show's a default and 3 other inactive links. Finally plugins where nothing seems wrong. All there as I remember. Some of my extensions seem to be working properly but others don;t How can I access these extensions and how do I get onto the add-on page?

It is possible that there is a problem with files in the profile folder that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox menu button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this didn't help then delete addons.json and possibly prefs.js in case there is a problem with preferences.

You can use this button to go to the current Firefox profile folder:

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?

Did you check for issues with the extensions files in the profile folder like I posted above?

As I said before some are working some not it's only visibility that's the problem. If I turn them off and start in safe mode and it doesn't change how do I turn them back on. I am not very experienced with computer workings only a tinkerer.

This is likely a problem with the extensions.* files in the Firefox profile folder, so you would have to check this out.

You can use this button to go to the current Firefox profile folder:

Note that "AppData" (XP: Application Data; Mac: ~/Library; Linux: ~/.mozilla) is a hidden folder.

Windows hides some file extensions by default. Among them .html and .ini and .js and .txt and you may only see a file name without file extension. You can check the file extension (type) in the properties of the file in Windows Explorer via the right-click context menu or have the File type column visible.

As already stated I am not very experienced with computer workings only a tinkerer. cor-el I thank you for your help but this is a little deep and before I thy it I need to make sure I have back-ups to do first in the next few days. My problem is not presently causing difficulties so I am not going to rush into an area I'm not comfortable with.

Do not worry. Those files will be re-created by Firefox.

Thank you cor-el and FredMcD. I have done nothing with this due to personal problems at home and as most of the add-on were working I didn't rush to try your suggestions but an update on Facebook yesterday took care of that and wiped all my customization and add-ons so now I do have to do something. Will let you know the result.

Are you saying you updated Firefox, and lost your profile?

Look on your desktop. Do you see a folder called; Old Firefox?

I think I found this problem. The update didn't cause loss of anything. What it did was turned off the add-on toolbar at the bottom of the page and what confused me was the Icon for add-on called Autofill forms was repositioned. It's usually in that toolbar.

Do you mean the add-ons bar at the bottom of the Firefox windows? The add-on bar was removed during one update by Mozilla for reasons no one understands. In some cases leaving lots of icons homeless.

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for an add-on bar.

Many of us are using; Classic Theme Restorer (Customize Australis) {web link} Restore squared tabs, appmenu, add-ons bar, small button view and more on Australis UI (Windows/MacOSX/Linux + Fx 29+).

This will restore many of the things the last upgrades took away.

You should be able to access it's settings thru the Add-ons Manager.

My original post started "When I click the add-on button Firefox opens on a blank page with my add-on links on the left hand side. It opens selecting 'get add-ons' and all that shows is a box saying 'loading' and the rotating icon. They never load. Going down the links the next is 'extensions' resulting in a blank page and nothing else" This is the add-on manager you mention and I have already it doesn't allow access. I am starting to feel as if we have gone full circle. I will try your solution in the next few days and let you know the outcome.

Type chrome://mozapps/content/extensions/extensions.xul?<enter> in the address bar. Are the add-ons displayed? Disable Everything. Then restart Firefox. Is the manager working not?
