Ako preglednik opet ne bude radio dobro, otvorit ću poveznicu na drugom računalu.

Because after ako when you are talking about a future condition, Croatian very often uses future II in the if clause.

So:

• Ako ... ne bude radio ... = If ... is not working / if ... doesn’t work in the future

This is more standard than using future I after ako. You may hear other patterns in everyday speech, but ako + future II is the textbook structure for future conditions.

Bude radio is future II.

It is formed with:

• budem, budeš, bude, budemo, budete, budu
• plus the l-participle of the main verb

Here the main verb is raditi, so the participle is:

• radio for masculine singular
• radila for feminine singular
• radilo for neuter singular

It is radio because the subject is preglednik, which is a masculine singular noun.

So:

• preglednik bude radio
• but aplikacija bude radila

This is an aspect question.

• raditi is imperfective
• otvoriti is perfective

Croatian uses imperfective when talking about an ongoing process or state, such as something working or functioning.

Croatian uses perfective when talking about a single completed action, such as opening a link once.

So the contrast is very natural:

• ne bude radio dobro = it will not be functioning well
• otvorit ću = I will do one complete action of opening it

In standard Croatian spelling, when the future auxiliary comes after the infinitive, the final -i of the infinitive is dropped in writing.

So:

• otvoriti + ću → otvorit ću

Compare:

• Otvorit ću poveznicu.
• Ja ću otvoriti poveznicu.

In the second example, the auxiliary comes before the infinitive, so the infinitive stays complete: otvoriti.

Because Croatian often drops subject pronouns when they are already clear from the verb form.

Here ću tells you the subject is I:

• otvorit ću = I will open

So ja is not necessary unless you want emphasis or contrast:

• Ja ću otvoriti poveznicu, ne ti.

Poveznicu is accusative singular.

The base form is:

• poveznica = nominative singular

It becomes poveznicu because it is the direct object of otvoriti.

You are opening what?

• poveznicu

That is why the accusative is used.

Here računalu is locative singular.

The phrase na drugom računalu means something like on another computer. With devices, platforms, websites, and similar contexts, Croatian often uses na + locative to express where something is opened, shown, or used.

Forms here:

• računalo → računalu in locative singular
• drugo → drugom to match it

So:

• na drugom računalu = on another computer

Yes. Opet and ponovno are often very close in meaning.

In this sentence, opet means again.

You could also say:

• Ako preglednik ponovno ne bude radio dobro...

The difference is mostly stylistic:

• opet is very common and everyday
• ponovno can sound a bit more neutral or formal

Because dobro is an adverb, and it modifies the verb raditi.

The idea is:

• raditi dobro = to work well

If you used dobar, that would be an adjective, and it would describe a noun instead.

So:

• dobar preglednik = a good browser
• preglednik radi dobro = the browser works well

Yes, preglednik and poveznica are standard Croatian terms.

But in everyday speech, many people also use borrowed forms, especially in tech contexts:

• browser
• link

So you may hear both:

• preglednik / browser
• poveznica / link

If you want more standard or formal Croatian, preglednik and poveznica are excellent choices.

Yes, Croatian word order is fairly flexible, although not completely free.

This sentence could also appear as:

• Ako opet preglednik ne bude radio dobro, otvorit ću poveznicu na drugom računalu.
• Ako preglednik opet ne bude radio dobro, poveznicu ću otvoriti na drugom računalu.
• Otvorit ću poveznicu na drugom računalu ako preglednik opet ne bude radio dobro.

The basic meaning stays the same, but the emphasis changes a little.

One important point: ću is a clitic, so its placement follows Croatian clitic rules. Also, when the ako clause comes first, it is normally separated from the main clause with a comma.
