User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053622

Steps to reproduce:

On answers.microsoft.com at this link


Click on reply to leave a reply to a previous post - a semi transparent white overlay covers the page.  It prevents me leaving a reply.

Adblock Plus development build beta
Filters are easylist and adblock warning removal list
Firefox 55.0.3 32 bit

Actual results:

If ABP is either enabled or disabled by clicking on the APB icon and choosing disable on this site, even with a restart I am unable to leave a reply in the thread, a semi transparent white overlay covers the page. 

Only if I go to Firefox - add-ons - and completely disable ABP and restart Firefox am I able to leave a reply. 

Further info from mapx at the AdBlock plus forum.......

Well, it's weird.
In FF 54 + the legacy ABP is working fine.

In FF 56 - even disabling the adblocker and restating FF - does not work.
Could be some FF regression due to the new extensions system.

Expected results:

I should have been able to leave a reply using Firefox 55.0.3 without having to disable AdBlock Plus and restarting Firefox.  The site worked well with all previous versions of Firefox up to 54.
Please report the issue to the extension author. Thank you!

It's not an extension issue.

Use for example FF 56.0b9 (64-bit)
Disable your adblocker(s) (from add-ons page).

Go to https://answers.microsoft.com/en-us/outlook_com/forum/oemail-ocompose/can-no-longer-expand-group-to-show-all-email/50cf8ce5-822e-44d8-8c15-3a6b2a741c6e?auth=1

Click Reply ==> on page overlay will appear. 

No such issue using chrome browser.
In which case the author of ABP will be able to explain exactly what it's doing to cause this issue and raise his own bug describing in much more detail what Firefox add-on API functions are being called that cause this. If you can do that you can reopen the bug.

ok, it's not about ABP.

It happens whatever extension you have enabled (tested with ABP / uBo / tampermonkey).

So, probably is still this bug ==> https://bugzilla.mozilla.org/show_bug.cgi?id=1379148

So, it's not invalid but duplicate.

I'm having this same problem which appears to be caused by the add-ons uBlock Origin and Bitwarden.  When I disable both of them the page loads.  Experimented on a clean profile with only these two add-ons.
