Android Mozilla FireFox not opening page in a new tab

Question

We have a link that we get from server (Url) and we want to open it in new window. We are using following code to do that:

<a class="block img-holder usedsearch-img-holder position-rel no-direct" target="_blank" href='/m@(Url)'>

This is working fine but is not opening new window in mozilla firefox. I read similar issue and workaround by using onclick here.

Only problem is that bots (especially non-google search engines) might not be able to index these pages. How can we achieve both i.e. open link in all browsers w/o javascript dependency?

I don't see issue on my test. If href value is coming from server code, please post whole HTML tag. – Brawner

i am testing on mozilla firefox v 56.0, device android, – Correll

Please post whole a tag after server rendering. The href value might have some invalid characters. – Brawner

<a class="listingTxt block text-default no-direct" id="listingTxt" title="Honda City 1.5 S MT" profileid="D1405814" target="_blank" href="/m/used/cars-in-mumbai/honda-city-2011-2014-d1405814/">TestLink</a> – Correll

Link is ok. Go to about:config in FireFox browser and turn on the required setting that you found best match – Brawner

Not working. It's already 0. – Correll
