Cannot download. Any attempts seem to go nowhere. Safe mode works. I have no addons enabled. I did try deleting mimeTypes.rdf

I cannot download anything. Clicking any file link produces no results. Same in gmail or anywhere. Right clicking a link does allow "save as" and that works. Destination folder for downloads IS writable and i can directly "save as" there. This broke suddenly tonight (during a browsing session - i was able to download one file but not the next), before this it worked for eons . If i start firefox in safe mode it does work. Another similar issue suggested deleting mimeTypes.rdf in profile folder. I tried that. no joy. Deleting my entire profile is *100% not an option*. I disabled all add-ons (adblock and ghostery) but it did not help.

Just so that you know, making multiple posts on the same question without any other responding could give the impression that you are being helped by someone.

Next time, just post one question and wait for a response.


As to the problem, is this on many websites, some, a few?

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

All websites. every single one. and like I said above - safe mode does work, but normal mode does not

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.


This download manager works separately from the browser. The browser tells it what to download, and off it goes.

1. I do not see how hardware acceleration could affect downloading files (I work in software, not in farming). But for the sake of argument, i disabled it and as expected It had no effect. It is clearly some setting that went wonky.

Note that Firefox no longer uses mimeTypes.rdf, but uses handlers.json.

You can try to rename prefs.js (prefs.js.sav) to see if that has effect to reset all preferences. If this didn't work then undo/reverse the rename and restore the previously used prefs.js.

deleting prefs.js did not help, ditto for handlers.json
