[Firefox Mobile] option buttons sometimes empty in addon properties

[WalterWW]

Sometimes the buttons display correctly, sometimes the text is missing:

I didn't notice strings were added to messages.json... Can you confirm your language is not English?

[Snow8]

Having the same issue too sometimes. Dunno what causes it tbh. My language is set to English.

[WalterWW]

Language is set to English.

[gorhill]

Ok maybe there is something else, but one thing is for sure, all translations are missing for these strings.

I can reproduce.

1.) Go to about:addons
2.) Disable uBlock
3.) Enable uBlock

The 2 buttons are blank like in the screenshot from @WalterWW . Clicking on them does nothing.

@my-password-is-password Most probably there is an error which prevents the extension to be initialized. Can you view the console errors in Fennec somehow?

Edit: maybe on this address: chrome://global/content/console.xul

@Deathamns Sorry for taking long to replay. Had to boot into win 7 to be able to see my phone the computer.

Have no idea if these belong to ublock.

[my-password-is-password]

Ok this is what a got after clearing the console, disable ublock, and then re-enable ublock.

[Deathamns]

tab.hasAttribute is not available on Fennec (fixed in ac09dfa), however I don't think that prevented the extension from loading.

No other error appears when you enable the extension?

[my-password-is-password]

Nope. Tried it again and its the same 4 lines in the console ( 2nd screenshoot ).

@Deathamns This happens on desktop Firefox too.

[gorhill]

When refreshing the page the buttons appear correctly.

[Deathamns]

I see. Those buttons are activated/filled only when you navigate to this page, because currently we detect when this page opens..

[gorhill]

Fixed with 90295e7.

Using 0.9.2.0 on firefox mobile, the buttons are still sometimes empty.

To reproduce it seems to be enough to open a few tabs, then close all but one and open the tools-addons menu from the dropdown list.

I haven't been able to reproduce this, perhaps you could give more detailed steps? What I did:

• Start Firefox Mobile
• Click the New Tab button 5 times
• Click the Close Tab button 5 times
• Click the Tools/Addons menu item
• Click the uBlock addon entry

[WalterWW]

Try opening actual websites with new tabs and not just empty tabs...

Sorry, still makes no difference if I insert a step 3 of navigating to google.com (for example). Perhaps you can pin down a minimal case? Starting with Firefox closed, is there a certain number of tabs required - does it happen with just two (the initial, and one opened)? Does it only happen for certain sites? Does the order matter?

[WalterWW]

Yeah, I have to admit that it's not easy to consistently reproduce. But it always happens after opening and closing a few websites in new tabs.

Try this: (see edit first)

1. go to https://github.com/gorhill/uBlock/releases
2. long press on that little i for issues to open the issues page in a new tab
3. switch to that tab and then close it
4. open about:addons from the dropdown and open ublock
5. are the buttons empty? if yes, success! if no, close the ublock tab, go to step 2 and repeat until success

I just did this a few times and it seems to happen after about the 4th iteration.

edit: I just figured that it's probably enough to just repeatedly opening the about:addons tab from dropdown, checking ublock, closing the tab and repeating until the buttons are empry. Seems to reproduce the issue as well, so no reason to bother with all the above steps.
